With continued reference to Fig. 2, the process of one embodiment of the method for handling video according to the disclosure is shown 200.The method for being used to handle video, comprising the following steps:

Step 201, target video is obtained.

In the present embodiment, can lead to for handling the executing subject (such as server shown in FIG. 1) of the method for video Wired connection mode or radio connection are crossed from remotely-or locally obtaining target video.Wherein, target video is to it The video handled.

In practice, target video can be the video that is shot and be obtained to actual scene.

Step 202, the quality value sequence of target video is generated.

In the present embodiment, based on target video obtained in step 201, target video is can be generated in above-mentioned executing subject Quality value sequence.Wherein, the element in quality value sequence be used to characterize time point in the time shaft of target video and with this Time point corresponding mass value.

Specifically, the time shaft of target video can be used for connecting to video frame according to the sequencing of time, obtain To target video.It is appreciated that while shooting obtains target video, it can determine the time shaft of target video.Practice In, the minimum unit on time shaft can be 1 second, i.e., be divided between two neighboring time point 1 second on time shaft.As an example, The starting point of time shaft can be 00:00 (0 point and 0 second)；First time point can be 00:01 (0 point and 01 second)；Second time point It can be 00:02 (0 point and 02 second)；Third time point can be 00:03 (0 point and 03 second) ....

In the present embodiment, the element in quality value sequence is arranged according to the sequencing of time.In quality value sequence Time point corresponding to element can be continuous time point on time shaft, or at discrete time point, not limit herein System.Specifically, time point corresponding to element in quality value sequence can be predetermined for technical staff, on a timeline Time point in predeterminated position, or whole time point on time shaft, or may be random from time shaft Determining time point.

In the present embodiment, mass value is used to characterize the quality of the video frame at the time point in time shaft.Specifically, The video frame at the time point in time shaft can be at the time point and in time shaft, adjacent with the time point be next The video frame that shooting obtains in period composed by time point.For example, being in the time for " 00:02 " this time point The video frame of point can be the video frame of the shooting acquisition within " 00:02-00:03 " this period.

In the present embodiment, mass value corresponding to the time point in quality value sequence can be by being in the time point The quality of video frame determines.Specifically, as an example, for time point corresponding to the element in quality value sequence, it is above-mentioned to hold Row main body can obtain the video frame in the time point first, then determine the video frame quality of acquired each video frame Value finally carries out mean operation to identified video frame mass value, obtains operation result as matter corresponding to the time point Magnitude.Here, video frame mass value can be used for characterizing the quality of video frame.Specifically, video frame mass value is bigger, it can be with table The quality for levying video frame is more excellent.

Here it is possible to the video frame mass value of video frame be determined using various methods, for example, can use existing image Quality Identification model determines the video frame mass value of video frame.

In some optional implementations of the present embodiment, above-mentioned executing subject can generate target by following steps The quality value sequence of video: firstly, for the time point in time shaft corresponding to target video, above-mentioned executing subject can be held Row following steps: destination number video frame is chosen from the video frame in the time point；Selected target is determined respectively The video frame mass value of quantity video frame；Based on identified destination number video frame mass value, the time point institute is determined Corresponding mass value.Then, above-mentioned executing subject can be according to the sequencing at corresponding time point, to identified quality Value is arranged, and quality value sequence is generated.

In this implementation, destination number can be predetermined quantity, or based in the time point Video frame quantity determine quantity (for example, in the time point video frame quantity half).Specifically , above-mentioned executing subject can choose destination number video frame using various methods, such as can be using the side randomly selected Formula is chosen, alternatively, can choose according to the sequencing of time.

Herein, above-mentioned executing subject can determine the video frame quality of video frame using above-mentioned picture quality identification model Value.In addition, in some optional implementations of the present embodiment, for the video in selected destination number video frame Following steps can also be performed in frame, above-mentioned executing subject: carrying out Laplace transform to the video frame, obtain transformation rear video Frame；Determine the variance of the pixel value of the pixel in transformation rear video frame；Identified variance is determined as to the view of the video frame Frequency frame mass value.

In practice, the region flat for image (region of the gray value without transformation), the image after Laplace transform exists The intensity value in the region is 0.At the region that gray value of image acutely converts (edge), the intensity of the image after Laplace transform It is relatively large to be worth (absolute value).Therefore, Laplace transform is commonly used for the marginal information of detection image.It in turn, can be with Understand, for the video frame (transformation rear video frame) of edge enhancing, variance is bigger, and the edge that can characterize video frame is more clear, And then the quality that can characterize video frame is more excellent.

In this implementation, above-mentioned executing subject can be adopted based on identified destination number video frame mass value With various methods determine the time point corresponding to mass value.For example, can be to identified destination number video frame quality Value carries out mean operation, obtains operation result as mass value corresponding to the time point；Alternatively, destination number can be regarded Maximum video frame mass value is determined as mass value corresponding to the time point in frequency frame mass value.

Specifically, for mass value corresponding to identified time point, above-mentioned executing subject can according to time point by Sequence after arriving first arranges identified mass value, generates quality value sequence；Alternatively, can according to time point after to Preceding sequence arranges identified mass value, generates quality value sequence.

Step 203, in response to determining that quality value sequence includes at least two local maximums, from least two local maximas Two adjacent local maximums are chosen in value.

In the present embodiment, based on the quality value sequence obtained in step 202, above-mentioned executing subject can be in response to determination Quality value sequence includes at least two local maximums, and two adjacent local maximas are chosen from least two local maximums Value.Wherein, in quality value sequence, adjacent with local maximum mass value be less than local maximum.

It is appreciated that when being shot using camera, if the target of expectation shooting changes, in order to continue to shoot New target, may move camera, so that target is contained in coverage.In this case, the movement of camera Meeting is so that the clarity for the video frame that shooting obtains is low, correspondingly, so that the mass value that shooting obtains video frame is small.When target packet When contained in coverage, camera then may be at relatively steady state, at this point, the clarity for the video frame that shooting obtains Height, correspondingly, the mass value that shooting obtains video frame are big.And when needing handoff scenario, when shooting new target, then need again Dollying head in this case, shoots the clear of the video frame of acquisition so that the fresh target of switching is contained in coverage Clear degree can decline, and correspondingly, the mass value that shooting obtains video frame reduces.When the fresh target of switching is contained in coverage When, camera can then be again at relatively steady state, and the clarity for shooting the video frame of acquisition can increase again, accordingly Ground, the mass value that shooting obtains video frame can become larger.

In turn, in the present embodiment, local maximum can correspond to relatively stable at camera in shooting process State, and quality value sequence include at least two local maximums, camera in shooting process can be characterized and occurred at least Variation from moving condition to metastable state twice can characterize in turn and scene switching occurred.Also, adjacent two The change procedure of mass value between a local maximum can correspond to the process of scene switching.

Particularly, since local maximum usually corresponds to the metastable state that camera is in shooting process, Shooting initial phase and shooting ending phase do not correspond to local maximum usually, and in turn, in the present embodiment, local maximum can Think and be corresponding with two adjacent mass values in quality value sequence, and is greater than the quality of two corresponding, adjacent mass values Value.

Herein, above-mentioned executing subject can choose two adjacent local maximums using various methods.Specifically, working as When only including two local maximums at least two local maximums that quality value sequence includes, above-mentioned executing subject can be straight Selecting takes the two local maximums.When at least two local maximums include at least three local maximums, at least Every two adjacent local maximum in three local maximums, above-mentioned executing subject choose the two adjacent local maximas Value composition local maximum group.

As an example, quality value sequence is " 3；8；2；6；4；5；7；1 ", wherein " 2 " and " 3 " adjacent with " 8 " are respectively less than " 8 ", so " 8 " are local maximum；" 4 " and " 2 " adjacent with " 6 " are respectively less than " 6 ", so " 6 " are local maximum；With " 7 " adjacent " 1 " and " 5 " is respectively less than " 7 ", so " 7 " are also local maximum.As can be seen that quality value sequence includes part Maximum value " 8 ", " 6 ", " 7 ".In turn, above-mentioned executing subject can choose adjacent two local maximums " 8 " and " 6 " composition office Portion's maximum value group, and choose adjacent two local maximums " 6 " and " 7 " and form local maximum group.

In some optional implementations of the present embodiment, above-mentioned executing subject can also be from least two local maximas Two local maximums that adjacent and corresponding difference is more than or equal to preset threshold are chosen in value.

Herein, preset threshold can be pre-set numerical value.It continues the example presented above, is " 3 for quality value sequence； 8；2；6；4；5；7；1 " above-mentioned executing subject determines three local maximums " 8 ", " 6 ", " 7 ".Preset threshold can be 2.Then Since the difference of " 6 " and " 7 " is less than 2；The difference of " 8 " and " 6 " is more than or equal to 2, thus above-mentioned executing subject can choose " 8 " and " 6 " the two local maximums.

It is appreciated that difference is bigger, the adjacent corresponding scene of two local maximums can for different scenes Energy property is then bigger.Therefore, this implementation can more accurately determine out the different local maximum of corresponding scene, have Help more precisely carry out cutting to target video according to scene.

It should be noted that obtaining at least two local maximum groups (here, when above-mentioned executing subject is based on step 203 One local maximum group includes two adjacent local maximums) when, above-mentioned executing subject can be at least two parts Each local maximum group in maximum value group, executes subsequent step 204 and step 205.

Step 204, from mass value in quality value sequence, between selected adjacent two local maximum The middle the smallest mass value of determination.

In the present embodiment, based on adjacent two local maximum chosen in step 203, above-mentioned executing subject can be with The smallest quality is determined from mass value in quality value sequence, between selected adjacent two local maximum Value.

Continue the example in step 203, quality value sequence is " 3；8；2；6；4；5；7；1 ", three parts determined are most Big value is that " 8 ", " 6 ", " 7 " can determine then for " 8 " and " 6 " the two adjacent local maximums from quality value sequence Mass value between the two local maximums only includes " 2 ", it is possible to which it is right that " 2 " are directly determined as " 8 " and " 6 " institute The smallest mass value answered；For " 6 " and " 7 " the two adjacent local maximums, position can be determined from quality value sequence Mass value between the two local maximums includes " 4 " and " 5 ", then above-mentioned executing subject " 4 " can be determined as " 6 " and The smallest mass value corresponding to " 7 ".

It is appreciated that the smallest mass value between adjacent local maximum images during usually corresponding to handoff scenario Therefore the movement time point the most apparent of head regards target based on the smallest mass value between adjacent local maximum Frequency carry out cutting facilitate would be more accurately target video cutting be different scenes under video.

Step 205, the time point based on corresponding to identified the smallest mass value carries out cutting to target video, obtains Obtain cutting rear video.

In the present embodiment, based on time point corresponding to the smallest mass value determined in step 204, above-mentioned execution master Body can carry out cutting to target video, obtain cutting rear video.

Specifically, above-mentioned executing subject can use various methods pair based on time point corresponding to the smallest mass value Target video carries out cutting.For example, above-mentioned executing subject can the directly time point cutting corresponding to the smallest mass value, make It obtains video frame in target video, that shooting obtains before at the time point and shoots the video frame of acquisition after this point Separately constitute cutting rear video.Herein, it should be noted that the shooting of the time point corresponding to the smallest mass value is obtained The video frame obtained may include in cutting rear video composed by the video frame that shooting obtains before at the time point, can also It is shot in cutting rear video composed by the video frame of acquisition after this point with being contained in, herein with no restrictions.

In some optional implementations of the present embodiment, for the cutting backsight in cutting rear video obtained Frequently, the label of the available video features for being used to characterize the cutting rear video of above-mentioned executing subject, and to the cutting backsight Frequency and acquired label are associated storage.Wherein, video features can be the various features of cutting rear video, including but not It is limited at least one of following: size, corresponding scene, the sequence in cutting rear video obtained.Wherein, obtained Cutting rear video can be arranged according to the sequencing of time.

Specifically, above-mentioned executing subject can adopt obtains label in various manners, for example, for cutting backsight obtained Cutting rear video in frequency, above-mentioned executing subject can export the cutting rear video, then obtain user's input, cut for this Divide the label of rear video.Alternatively, the above-mentioned available pre-stored tag set of executing subject, and then cut for obtained Cutting rear video in point rear video, above-mentioned executing subject can be identified that (such as identification should to the cutting rear video first The size of cutting rear video, or identify sequence of the cutting rear video in cutting rear video obtained), obtain identification knot Fruit (such as sequence in second), then from tag set (such as " 1；2；3；4 ") it is obtained corresponding to the cutting rear video in Label (such as 2).

This implementation is facilitated based on label quickly, conveniently by being associated storage to label and cutting rear video Ground extracts the video clip (cutting rear video) of target video, in turn, helps to improve the efficiency of video processing.

In some optional implementations of the present embodiment, above-mentioned executing subject may also respond to receive communication link The video acquisition request that the user terminal connect is sent, executes following steps: based on mark corresponding to cutting rear video obtained Label choose cutting rear video corresponding with video acquisition request from cutting rear video obtained；By selected cutting Rear video is sent to user terminal, and control user terminal plays out selected cutting rear video.

Herein, video acquisition request may include the information (example for being used to indicate the video features of video of request Such as text " segment 1 "), and then above-mentioned executing subject can be based on label (such as " 1 "), select from cutting rear video obtained Take cutting rear video corresponding with video acquisition request.It is appreciated that cutting rear video corresponding with video acquisition request The as corresponding video features cutting rear video same or similar with the indicated video features of video acquisition request.

In this implementation, terminal that user terminal can use for user, with the communication connection of above-mentioned executing subject. In practice, above-mentioned executing subject can send control signal to user terminal, and then control user terminal to selected cutting Rear video plays out.

The cutting rear video being cut into according to scene can be sent to user terminal, and control user by this implementation Terminal plays out cutting rear video, with this, can control user terminal and pointedly plays according to scene and video acquisition Corresponding video is requested, in turn, the result of broadcast of video can be improved；Also, target video is played with control user terminal It compares, this implementation can reduce the waste of resource.
