Description
Technical field
The embodiment of the invention relates to image processing field, and more specifically, relates to the method and apparatus that obtains the image block that is used for merging patterns.
Background technology
In video coding and decoding framework, the hybrid coding structure is generally used for the Code And Decode of video sequence.The coding side of hybrid coding structure generally includes: prediction module, conversion module, quantization modules and entropy coding module; The decoding end of hybrid coding structure generally includes: entropy decoder module, inverse quantization module, inverse transform block and predictive compensation module.The redundant information of video sequence can be effectively removed in the combination of these Code And Decode modules, and can guarantee to obtain in decoding end the coded image of video sequence.
In video coding and decoding framework, the image of video sequence is divided into image block usually and encodes.Piece image is divided into some image blocks, and these image blocks use above-mentioned module to carry out Code And Decode.
In above-mentioned module; Prediction module is used for the predict blocks information that coding side obtains the image block of video sequence coding image; And then obtain the residual error of image block; The predictive compensation module is used for the predict blocks information that decoding end obtains current decoded image blocks, and the image block residual error that obtains according to decoding again obtains current decoded image blocks.Prediction module comprises infra-frame prediction and two kinds of technology of inter prediction usually.Wherein, infra-prediction techniques utilizes redundant information that the aerial image prime information of current image block removes current image block to obtain residual error; Inter prediction techniques make use present image is contiguous encode or the decoded picture Pixel Information remove current image block redundant information to obtain residual error.In the inter prediction technology, the contiguous image of present image that is used for inter prediction is called as reference picture.
In the inter prediction technology, coding side need obtain the image block the most similar with current image block in order effectively to remove the redundant information of current image block in reference picture, and then reduces the residual error of current image block.Coding side uses estimation to obtain the image block in the above-mentioned reference picture usually.Motion estimation process is that suitable matching image piece is searched for by unit in when coding in reference picture with the image block usually in existing video coding and decoding technology; Current macro and matching image piece institute respective pixel value subtracted each other obtain residual error; And with this residual error through conversion with quantize after the value that obtains carry out entropy coding; The bit stream that at last entropy coding is obtained writes in the encoding code stream, and the side-play amount (being motion vector) that also will search for gained simultaneously writes in the encoding code stream in the lump.Corresponding therewith;, the decoding end predictive compensation carries out the entropy decoding after at first obtaining the entropy coding bit stream when (or claiming motion compensation); Obtain corresponding residual error, and corresponding motion vector, afterwards; In reference picture, obtain corresponding matching image piece (the both predict blocks information of above-mentioned current decoded image blocks) according to motion vector value, the value addition with corresponding pixel points in image block that matees and the residual values obtains the decoded value of current macro again.
In existing video encoding and decoding standard; Like MPEG-2, H.264/AVC, an image block; Or be called macro block (macroblock), supermacro piece (super-macroblock) etc.; Be divided into the plurality of sub image block, the size of these subimage blocks can be 64 * 64,64 * 32,32 * 64,32 * 32,32 * 16,16 * 32,16 * 16,16 * 8,8 * 16,8 * 8,8 * 4,4 * 8,4 * 4 etc., and subimage block carries out above-mentioned estimation and motion compensation with these sizes.These subimage blocks are the rectangular block of N * M (N and M are the integer greater than 0) in existing video encoding and decoding standard, and N and M have the multiple relation.
The shortcoming of image block and subimage block coding mode is not have well to consider the space or the temporal continuity of moving object in the image or image texture in the existing video encoding standard.What object in the image and texture were often corresponding is not only an image block or subimage block; And probably corresponding to the areas with irregular continuously of a slice on time or the space; Therefore on some direction in image, adjacent image piece or subimage block possibly belong to same object simultaneously or have with a kind of textural characteristics.At this moment; If the mode of N in the employing existing standard * M rectangular block is carried out inter prediction encoding; So when obtaining the motion vector of current image block or subimage block; Cause error to increase thereby might be referenced to the motion vector that does not belong to same object or texture region of the same race, this in addition coded system can not make full use of the movable information of the adjacent image piece that belongs to same object or textural characteristics.
To the problems referred to above, in the video coding framework, introduced the decoding method of a kind of image block or subimage block merging patterns.The method of image block merging patterns is meant when current block carries out the interframe encoding and decoding; Directly take out and the movable information of image block that the present encoding piece is adjacent in time domain or spatial domain or subimage block as the movable information of current image block, wherein comprise the number of motion vector, reference frame index and reference picture etc.Adopting image block or all motions of subimage block of merging patterns is that information all comes from above-mentioned adjacent image block or subimage block, and this moment, current image block or subimage block did not need any motion vector information of encoding again.Adjacent image block is meant: in the space, be positioned at the image block of the current encoding and decoding piece left side, top, upper left side, lower left, perhaps on time domain, be arranged in the image block that previous coded image and present encoding piece have common location.If the adjacent image piece of certain position does not exist, or not encoding and decoding as yet, perhaps use the intra prediction mode coding, it is unavailable then to be called image block, abandons this adjacent image piece.Present existing technology has adopted 5 possible adjacent image pieces; Be respectively in left side piece, top piece, the former frame and image block, upper right side image block and the lower left image block of current block with common location, these possible adjacent image pieces are called as the candidate image piece.
Because it is a plurality of that the available candidate image block of current encoding and decoding image block possibly exist, so current image block need use extra identification means to be used to identify the label (0-4) of the adjacent image piece that current image block adopts.At present the identification method in the prior art has combined the adjacent block number that current image block can use and the label of the employed adjacent image piece of current image block, when available adjacent image piece is 1, does not identify; When available adjacent image piece is 2, adopt 1 bit (bit) sign; When available adjacent image piece is 3 or 3 when above, adopt variable-length encoding (1-4 bit).
Left image piece adjacent and top image block have only been checked when using merging patterns to obtain the left side and top candidate image piece in the prior art with the current image block upper left corner; When the left image piece adjacent with the current image block upper left corner or top image block are unavailable, think that then the left side or top candidate image piece can not obtain, the candidate image piece number that can be used for merging patterns can reduce.If only obtain and check the reference image block of the left side and top merging patterns in a manner described, thereby then cannot utilize the movable information of adjacent image piece to influence coding efficiency well.
Summary of the invention
The embodiment of the invention provides a kind of method and apparatus that obtains the image block that is used for merging patterns, can improve coding efficiency.
According to an aspect of the present invention, a kind of method of obtaining the image block that is used for merging patterns is provided, has comprised: on the current image block left side or top when having at least two adjacent blocks, obtained adjacent block according to predefined procedure; The adjacent block of confirming to meet pre-defined rule is the image block that is used for merging patterns.
According to a further aspect in the invention, a kind of equipment that obtains the image block that is used for merging patterns is provided, has comprised: acquiring unit, be used on the current image block left side or top when having at least two adjacent blocks, obtain adjacent block according to predefined procedure; Confirm the unit, the adjacent block that is used to confirm to meet pre-defined rule is the image block that is used for merging patterns.

Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Fig. 1 has described the sketch map of the position of candidate image piece under the merging patterns.As stated; Present existing technology has adopted 5 possible adjacent image pieces (candidate image piece); Be respectively in left side piece, top piece, the former frame and image block, upper right side image block and the lower left image block of current block, in Fig. 1, be labeled as b1-b5 respectively with common location.
Only obtain and checked left image piece adjacent and top image block when using merging patterns to obtain the left side and top candidate image piece in the prior art with the current image block upper left corner; When the left image piece adjacent with the current image block upper left corner or top image block are unavailable, think that then the left side or top candidate image piece can not obtain, the candidate image piece number that can be used for merging patterns can reduce.And in fact when the left image piece adjacent with the current image block upper left corner or top image block are unavailable, still possibly there are available image block in other left side or the top image block adjacent with current image block.
Fig. 2 is a sketch map of having described the adjacent image piece of current image block.In the accompanying drawing of Fig. 2 and back, inter representes that this image block is " inter-coded block ", and intra representes that this image block is " Intra-coded blocks ".As shown in Figure 2, the left image piece adjacent with current image block CB has four, and label is Lblk0 to Lblk3.Be not useable for merging patterns though Lblk0 is an Intra-coded blocks, Lblk1 to Lblk3 is an inter-coded block, can be used for merging patterns.In like manner, top image block adjacent with current image block among Fig. 2 has four, and label is Tblk0 to Tblk3, is not useable for merging patterns though Tblk0 and Tblk1 are Intra-coded blocks, and Tblk2 and TLblk3 are inter-coded block, can be used for merging patterns.Because the basic point of departure of merging patterns is that current image block CB belongs to same object or has similar texture with the adjacent image piece, so they can share movable information (containing the number of motion vector, reference frame index and reference picture etc.).And, because Lblk1 to Lblk3, Tblk2 to Tblk3 are all adjacent with current image block, these image blocks and might be adjacent with current image block CB, so they also can be used in the merging patterns.If only check the reference image block of the left side and top merging patterns, thereby then cannot utilize the movable information of adjacent image piece to influence coding efficiency well by the mode of above-mentioned Fig. 1.
Fig. 3 is the schematic flow diagram of method 30 that is used for the image block of merging patterns according to obtaining of the embodiment of the invention.Method 30 is mainly used on the current image block left side or the situation of top when having at least two adjacent blocks.
At the S32 of method 30, obtain said adjacent block according to predefined procedure.Then at S35, the adjacent block of confirming to meet pre-defined rule is the image block that is used for merging patterns.
Like this; The embodiment of the invention is when the image block of the left side that obtains merging patterns and top; Be not limited to left side piece b1 shown in Figure 1 and top piece b5 or left side piece Lblk0 and top piece Tblk0 shown in Figure 2; But order is obtained a plurality of adjacent blocks of the current image block left side or top, thereby obtain available candidate blocks as much as possible.Because available candidate blocks number increases, thereby the image block that guarantees more likely to obtain to belong to an object together with current image block or have a similar texture is using in merging patterns, thus the raising coding efficiency.
Below in conjunction with specific embodiment the different modes that obtaining of the embodiment of the invention is used for the image block of merging patterns is described.Fig. 4 is the sketch map that obtains the mode of image block according to an embodiment of the invention.Fig. 4 is an example that is used to obtain the usable image piece of the left side and top.

The embodiment of Fig. 5 also includes lower left corner candidate blocks LBblk or upper right corner candidate blocks RTblk in and obtains in the order.
Particularly, when obtaining the image block on the left side, list the candidate blocks LBblk in the current image block CB lower left corner in left side adjacent block obtaining in the order; Image block RTblk with the image block CB upper right corner when obtaining the top image block lists obtaining in the order of top adjacent block in.As shown in Figure 5, obtain Lblk0, Lblk1, Lblk2, Lblk3 and LBblk successively by from top to bottom order when obtaining the left image piece, judge whether that available rule is the same.In like manner, as shown in Figure 5, obtain Tblk0, Tblk1, Tblk2, Tblk3 and RTblk successively by from left to right order when obtaining the top image block, judge whether that available standard is the same.
The above-mentioned order of obtaining is predefined and various ways arranged, and when obtaining the left image piece, obtaining order can be for from top to bottom, also can be from the bottom up, and also can obtain by order at interval; When obtaining the top image block, obtaining order can also can turn left from the right side for from left to right, and also can obtain by order at interval.
According to embodiment shown in Figure 5,, can reduce the coded-bit number owing to need not to be provided with the candidate blocks that independent bit is represented the upper right corner and the lower left corner.
Fig. 6 is the sketch map that obtains the mode of image block according to another embodiment of the present invention.
In Fig. 6, also adopt above-mentioned similar obtain manner to confirm to left hypograph piece or upper right image block.Particularly, can be starting point from LBblk obtain the image block that first is available as left hypograph piece by order from the bottom up to the obtain manner that obtains left hypograph piece; The obtain manner that obtains upper right image block can be that starting point is obtained the image block that first is available as upper right image block by the order of turning left from the right side from RTblk.As shown in Figure 6, obtain LBblk and LBblk3 image block successively. first available image block is as the left hypograph piece that is used for merging patterns; Obtain RTblk and Tblk3 successively, first available image block is as the upper right image block that is used for merging patterns.Simultaneously, obtain Lblk0, Lblk1 and Lblk2 successively, first available image block is as the left image piece; Obtain Tblk0, Lblk1 and Lblk2 successively, first available image block is as the top image block.
The different examples of the method that can use the embodiment of the invention have been described above.The equipment that is used for the image block of merging patterns according to obtaining of the embodiment of the invention is described below.Fig. 7 is the schematic block diagram of equipment 70 that is used for the image block of merging patterns according to obtaining of the embodiment of the invention.
