Detailed description of the present invention is mainly come the running of direct or indirect simulation technical scheme of the present invention through program, step, logical block, process or other symbolistic descriptions.Be the thorough the present invention that understands, in ensuing description, stated a lot of specific detail.And when not having these specific detail, the present invention then possibly still can realize.Affiliated those of skill in the art use these descriptions here and state that the others skilled in the art in affiliated field effectively introduce their work essence.In other words, be the object of the invention of avoiding confusion, because the understanding easily of method of knowing and program, so they are not described in detail.
Alleged here " embodiment " or " embodiment " are meant special characteristic, structure or the characteristic that can be contained at least one implementation of the present invention.Different in this manual local " in one embodiment " that occur not are all to refer to same embodiment, neither be independent or optionally mutually exclusive with other embodiment embodiment.In addition, represent that the sequence of unit and revocable in method, flow chart or the functional block diagram of one or more embodiment refers to any particular order, also be not construed as limiting the invention.
See also shown in Figure 1ly, it shows the block diagram of intelligent monitor system of the present invention.As shown in the figure, intelligent monitor system of the present invention comprises intelligent monitored control module, treats target area identifying unit, coding unit and decoding unit with a certain discrimination.
Said intelligent monitored control module can be arranged in the intelligent monitoring pick-up head; It can obtain the information of moving object detection and tracking; The sign of target number (ID) for example, various characterising parameters, the for example boundary rectangle of moving target, mask, movement velocity, relevant warning message etc.
Because in supervisory control system; Possible user is the zone that the moving target motion is arranged to the special zone of being concerned about of video quality; To the changeless background area of picture then is not special care; Therefore treat with a certain discrimination the background area that need not too be concerned about the moving target moving region and the user of user's care; Intelligent monitor system of the present invention treat the target area identifying unit with a certain discrimination, its moving target characterising parameter that obtains according to intelligent monitored control module is confirmed the motion target area and the background area that need to be treated differently.
Encode through coding unit through motion target area after judging and background area and since motion target area and background area receive degree of concern different, so when encoding, also be to carry out different coding discriminatingly.For example can distribute higher bit rate, treat motion target area and background area like this with a certain discrimination the special motion target area of being concerned about of user.The back will be told about in detail.
Through with the motion target area and the background area that are divided into special concern in the frame picture, carrying out different coding respectively like this, is reducible output picture after decoding through decoding unit through the data behind the coding again.
To the concrete steps of the method for encoding and decoding in the whole intelligent monitor system of the present invention be elaborated below;
See also shown in Figure 2ly, it shows the workflow diagram of intelligent monitor system according to an embodiment of the invention, and as shown in the figure its comprises the steps:
Step 21: intelligent monitored control module obtains the information of moving object detection and tracking; The information of wherein obtaining comprises the sign number (ID) of moving target and the various characterising parameters of moving target; Wherein said characterising parameter comprises the boundary rectangle of moving target, the grade of the mask of moving target, the movement velocity of moving target and type of alarm, attention rate of moving target image-region of living in or the like.
Step 22: the various parameters of the moving target that obtains according to functional monitoring module are confirmed the zone that needs to be treated differently.Because possible user is the zone that the moving target motion is arranged to the special zone of being concerned about of video quality; To the changeless background area of picture then is not special care, and treat with a certain discrimination the background area that therefore need not too be concerned about the moving target moving region and the user of user's care.Wherein step 22 further comprises two kinds of situation, and a kind of is that the object of motion and static background are treated with a certain discrimination.A kind of in addition situation is a moving target process zones of different, triggers different the warning and treats with a certain discrimination when being provided with:
To the step 221 that the object and the static background of motion are treated with a certain discrimination, as shown in Figure 3, it further comprises:
Step 2211: the boundary rectangle according to moving target obtains the cell block that intersects with said moving target.Because present video coding technique normally is divided into many with a frame picture, be based on all for the video coding technique of the picture of whole frame that block encoding realizes.As shown in Figure 4; Frame 41 among the figure is the boundary rectangle of moving target; And every frame picture is to be divided into some cell blocks; Through seeing among the figure, the boundary rectangle of moving target can intersect with a plurality of cell blocks, and just the frame of each moving target can occupy the picture of a plurality of cell blocks in the background.For example a moving target among the figure has just occupied a plurality of cell blocks such as cell block 42,43 in the frame.
Step 2212: the mask according to moving target obtains the cell block that intersects with the moving target mask.As shown in Figure 4; The image 44 of moving target is the mask of moving target among the figure; Cell block in its background that covers in the drawings promptly obtains the cell block that intersects with the moving target mask according to the mask of moving target; Obtaining the cell block that intersects with the moving target mask according to the mask of moving target in this step 2212 is moving target corresponding cells piece, therefore needs to be treated differently.
Step 2213: the cell block that obtains in cell block that obtains in the step 2211 and the step 2212 is compared; If obtain the cell block that intersects with the moving target mask less than obtaining the half the of the cell block that intersects with said moving target according to the boundary rectangle of moving target in the step 2211 according to the mask of moving target in the step 2212, then encoded in the position that obtains the cell block that intersects with the moving target mask according to the mask of moving target in the step 2212.With one of them moving target among Fig. 4 is example, and in Fig. 5 A, whole square frame then is the cell block that intersects with boundary rectangle moving target that obtain according to step 2211.The cell block that with moving target mask intersect of white portion in the middle of among the figure for obtaining according to step 2212.The cell block number of the white portion in figure is then encoded to the cell block of the white portion among the figure less than a half of the cell block number of whole square frame.
If obtain the cell block that intersects with the moving target mask greater than obtaining the half the of the cell block that intersects with said moving target according to the boundary rectangle of moving target in the step 2211 according to the mask of moving target in the step 2212; Then do not belong in the step 2212 cell block that mask according to moving target obtains the cell block that intersects with the moving target mask and encode, and be denoted as background obtaining the cell block that intersects with said moving target according to the boundary rectangle of moving target in the step 2211.Shown in Fig. 5 B, whole square frame then is the cell block that intersects with boundary rectangle moving target that obtain according to step 2211.The cell block that with moving target mask intersect of white portion in the middle of among the figure for obtaining according to step 2212.The cell block number of the white portion in figure is then encoded to the cell block of the black region among the figure, and these black unit pieces is denoted as background greater than a half of the cell block of whole square frame.The quantity of coding is that less cell block is encoded all the time like this, and the bit number that the required information of region description takies can be less.
To aforesaid another kind of situation, through zones of different, trigger the different steps 222 of reporting to the police and treating with a certain discrimination when being provided with at moving target, it further comprises:
According to the grade of the type of alarm in the goal description parameter or the attention rate of image-region of living in, when moving target process zones of different, can trigger different the warning and be provided with and motion target area is treated with a certain discrimination.If for example the alarm level of moving target reaches predetermined alarm level simultaneously; Then need when encoding, treat with a certain discrimination the image-region at current moving target place; When perhaps if moving target is through bank or golden shop near zone; The ratio that these regional attention rates are provided with is higher, and need treat with a certain discrimination these regional codings.
Wherein abovementioned steps 221 can all need be carried out with step 222, perhaps only carries out wherein a kind of step and gets final product.
Step 23: after the image-region of having confirmed to need to be treated differently, need encode, when image is encoded, because need take different coding to different zones to image.Can be divided into three kinds of coded systems this moment again.See also shown in Figure 6ly, these three kinds of coded systems are specially:
Method 1:, thereby can use meticulousr quantizing process to obtain the higher-quality image of relative background for the higher bit rate of moving target mask corresponding cells piece distribution ratio background cell piece that obtains in the abovementioned steps 2212.Will not encode by the motion target area characterising parameter this moment.Decoding end decoding back obtains the picture rich in detail of respective regions naturally.
Method 2: every frame was only encoded to the zone that needs to be treated differently that obtains according to step 22, and is not encoded in other zones in when coding, and after at interval certain frame, ability was encoded to background when perhaps background had certain variations.Because need to confirm the zone of treating with a certain discrimination, therefore this moment every two field picture code stream in the lossless coding of motion target area characterising parameter is all arranged.
Method 3: the moving target mask corresponding cells piece for obtaining in the abovementioned steps 2212 carries out enhance encoding, for example gives higher resolution to these cell blocks.This moment every two field picture code stream in the lossless coding of motion target area characterising parameter also as the part of enhance encoding.
Abovementioned steps method 1, method 2, method 3 are to treating three kinds of different coding modes in zone with a certain discrimination, in real process, can using wherein a kind of coded system arbitrarily.
Step 24: the image to after the coding is decoded with output image.
In wherein aforementioned three kinds of coded systems, method 1 and method 3 described methods do not need the special decode device.And for method 2 described coded systems, as shown in Figure 7, when decoding, comprise the steps:
Step 241: the motion target area characterising parameter of decoding present image; Boundary rectangle according to each target area that obtains after the decoding; And in the abovementioned steps 2213 to the decoding of the position of corresponding each cell block that needs to be treated differently of moving target mask, the position of each cell block that obtains treating with a certain discrimination.
Step 242: because during aforementioned coding, be that at interval certain frame or background are just encoded to background when changing, therefore, if present frame is a background frames, then to this frame background image updating afterwards of decoding.Otherwise continuation next step:
Step 243: the image of each cell block that decoding is treated with a certain discrimination is to the corresponding unit block position.
Step 244: decoded target area of treating with a certain discrimination and background image are merged, and form a complete image.
Video coding-decoding method of the present invention is treated moving target and target context with a certain discrimination according to the characterising parameter of the moving target that intelligent monitored control module obtains; And distinguish coding; Can reduce the data volume in the code stream, thereby under low code check situation, also can guarantee the requirement of user video quality.
Above-mentioned explanation has fully disclosed embodiment of the present invention.It is pointed out that any change that technical staff's specific embodiments of the invention of being familiar with this field is done does not all break away from the scope of claims of the present invention.Correspondingly, the scope of claim of the present invention also is not limited only to previous embodiment.
