According to the video processing method, the video processing device, the computing equipment and the media, under the condition that the image frame of the video to be processed contains the first target object, the image frame is processed through the second target object to obtain the processed video; and further, the processed video becomes a new video which can be repeatedly used in the later period, and the utilization rate of the video is improved.
In this embodiment of the present invention, the acquiring the image frame of the video to be processed in step 101 includes:
and acquiring image frames of the video to be processed frame by frame.
It should be noted that before the image frames are identified, the image frames of the video to be processed need to be acquired frame by frame.
In this embodiment of the present invention, the identifying, in step 102, an image frame including a first target object in the image frames of the video to be processed includes:
acquiring a first target object;
according to the acquired first target object, identifying image frames frame by frame, and determining the image frame containing the first target object and the position of the first target object in the image frame.
It should be noted that, before the identification, an object to be identified, i.e. a first target object, for example, "double 11" needs to be determined, and then an image frame containing "double 11" is identified from the video to be processed; after determining the image frame containing the "double 11", the position of the "double 11" in the image frame also needs to be determined.
It should be noted that, for a single image frame containing the first target object, the position of the first target object in the image frame is only required to be found; for a plurality of image frames containing the first target object, determining the time information of each image frame containing the first target object in the video to be processed; for example, for a 3s video to be processed, if the first target object exists at 2.5s, the corresponding time information is 2.5 s.
In an embodiment of the present invention, the processing at least the image frame containing the first target object by using the second target object in step 103 includes:
and replacing the first target object by using the second target object to generate an image frame containing the second target object.
In the embodiment of the invention, the second target object is used for replacing the first target object; and then the video to be processed can become a new video which can be repeatedly used in the later period, and the utilization rate of the video is improved.
In an embodiment of the present invention, the processing at least the image frame containing the first target object by using the second target object in step 103 includes:
the first target object is overlaid with a second target object, and an image frame containing the second target object is generated.
In addition, upon determining the position information of the first target object in the image frame, the first target object is replaced with the second target object at the position, so that the first target object is invisible.
In one example, in the case where the first target object is a picture, the first target object is overlaid with the second target object, and an image frame containing the second target object is generated.
It should be noted that the first target object includes, but is not limited to, a picture, a character gesture in a video, a text, and the like.
According to the embodiment of the invention, the second target object is covered on the first target object; and then the video to be processed can become a new video which can be repeatedly used in the later period, and the utilization rate of the video is improved.
In addition, upon determining the position information of the first target object in the image frame, the first target object is overlaid with the second target object at the position, so that the first target object is not visible.
In fig. 2, a video to be processed 21, a first target object 22, a second target object 23; the second target object 23 is covered on the first target object 21, so that the video 21 to be processed can be repeatedly used, and the utilization rate of the video is improved.
In one example, where only one image frame includes a first target object, overlaying the first target object with a second target object generates an image frame containing the second target object.
In fig. 3, a video to be processed 31 is identified, an image frame 32 including a first target object is identified, and a second target object 33 is overlaid on the image frame 32 of the first target object to form a new video.
In one example, in the case that a plurality of image frames in the video to be processed contain a first target object, the first target object is covered by a plurality of second target objects respectively, and an image frame containing the second target object is generated.
It should be noted that a plurality of second target objects may be the same, and each second target object covers a corresponding first target object; and then the video to be processed can become a new video which can be repeatedly used in the later period, and the utilization rate of the video is improved.
In the embodiment of the present invention, the processing at least the image frame containing the first target object by using the second target object in step 103 includes:
a second target object is superimposed on the first target object or a region in the vicinity of the first target object, and an image frame including the second target object is generated.
According to the embodiment of the invention, the second target object is superposed on the first target object; and then the video to be processed can become a new video which can be repeatedly used in the later period, and the utilization rate of the video is improved.
Wherein the second target object comprises one or more of pictures, characters or sounds
In fig. 4, a video to be processed 41 is identified, a first target object 42, e.g., "hand", contained in an image frame of the video to be processed is identified, and after the "hand" is identified, a second target object 43, e.g., "love heart", is superimposed at a position above the "hand".
It should be noted that the position of "love heart" can be superimposed at any position; in the embodiment of the present invention, the case of overlapping the "hand" is taken as an example; when the processed video is played subsequently, the user can feel 'love' only when playing the 'hand', so that the whole video is added with a new sensory effect and can attract attention.
In fig. 5, a video to be processed 51 is identified, a first target object 52, for example, a "hand", included in an image frame of the video to be processed is identified, and after the "hand" is identified, a second target object 53, for example, a dynamic "love heart", is superimposed at a position above the "hand", and a "kiss" sound effect is added.
During the playing process, if the first target object 52 is recognized, a "love heart", a dynamic "kiss" image and a sound effect "kiss" are presented on the page.
The area on or near the first target object may be an area above the first target object, or may be another area; the purpose of superposing the second target object on the first target object or the area near the first target object is to generate an image frame containing the second target, so that the video to be processed can become a new video which can be repeatedly used in the later period, and the utilization rate of the video is improved.
In one example, the second target object is a touch operation identifier, and the touch operation identifier is used for receiving a touch operation of a user when touched by the user.
The second target object is a touch component and/or audio acquisition equipment on the terminal. The terminal comprises a touch control assembly and an audio acquisition device, wherein the touch control assembly on the terminal is used for receiving an interactive behavior corresponding to a touch control operation identifier of a user, and the audio acquisition device is used for acquiring the interactive behavior corresponding to the touch control operation identifier of the user.
The video processing method further comprises: if the touch operation identifier set by the second target object is triggered by the user, displaying an interactive interface corresponding to the touch operation identifier so as to interact with the user; after a touch control assembly on the terminal receives an interactive behavior corresponding to a user and a touch control operation identifier, displaying an interactive effect corresponding to the interactive behavior on a terminal interface; or
In the process of playing the processed video by the terminal, if the interactive behavior corresponding to the touch operation identifier of the user is acquired through the audio acquisition equipment; and after the audio acquisition equipment on the terminal receives the interactive behavior corresponding to the touch operation identification of the user, displaying the interactive effect corresponding to the interactive behavior on the terminal interface.
The video to be processed is matched with the first target object (image-text and gesture) for image recognition, and the second target object (interactive module, image-text, sound information and the like) is added to the information layer of the recognized segment, so that a new sensory effect can be added when the processed video is played subsequently.
In fig. 6, after the processed video 61 is played, a terminal interface presents a character of "click to get a red packet" 62, and when a user clicks the character, an effective area of the interface invokes a feedback state, for example, a large red packet (i.e., an interactive effect) is presented on the whole interface, and the amount of money taken by the user is displayed.
It can be seen that the embodiment of the present invention generates an image frame containing a second target object by superimposing the second target object on the first target object or in the vicinity of the first target object; can add new sensory effect to the video to be processed and simultaneously improve the long-term utilization rate.
In this embodiment of the present invention, after the interaction is completed, the video processing method further includes: and after the interaction is finished, controlling the processed video to continue playing.
After the red packet display time in fig. 6 expires, the processed video will continue to be played; or the presentation of the red envelope may be ended in advance after the user manually clicks, and then the image frame containing the second target object is played.
In one example, the first target object includes: in the case where the first time information and the second target object include the updated first time information, step 102 specifically includes:
selecting a first target object, such as a word of 'No. 11 monthly promotion', and the like, identifying an image frame at least containing the first target object, and finding the first target object containing the 'No. 11 monthly promotion'; and covering the second target object (also containing updated first time information which accords with the current time, and assuming that the current time is 12 months and 12 numbers) on the first target object, so that the video containing the second target object can be continuously used at the later stage of the activity, and the utilization rate of the video is improved.
