Description

A kind of boundary intensity determines method, block-eliminating effect filtering method and device

Technical field

The present invention relates to communication technical field, more particularly to a kind of boundary intensity determine method, block-eliminating effect filtering method, And device.

In network environment（Such as internet）, because the network bandwidth is limited, the demand of terminal device and user All it is different, so for certain specific application, the code stream of first compression is not satisfactory and effective, to one It is even nonsensical for some specific users or equipment.An effective method for solving this problem is exactly SVC （Scalable Video Coding, scalable video）,JVT（Joint Video Team, joint video code set） Through then bringing SVC in the H.264/AVC extension of standard into, receive to be international standard by formal, and specify H.264/AVC the decoding syntactic structure of corresponding SVC code stream, includes H.264/AVC code used technologies of corresponding SVC Briefly introduce.In order to adapt to be actually needed, in HEVC in 2 months 2012 CD（COMPACT DISK, CD）After standard, development HEVC SVC is an extremely urgent thing.SVC based on HEVC is then referred to as by the JCT-VC meetings that in October, 2012 holds SHVC（Scalable Highefficiency Video Coding, scalable high-performance video coding）, start test job.

Predictive coding, transition coding are based on H.264/AVC all to be used as the primary video coding standard of representative with HEVC With the hybrid encoding frame of statistical coding.Under the framework, the quantization operation to residual unit after prediction is to cause Video coding The main cause of Quality Down.Information content difference is bigger between adjacent cells after prediction（I.e.：Residual difference is bigger）, be more possible to through Quantization/inverse quantization is crossed, mutation is introduced on the border of block, and blocking artifact therefore occur.H.264/AVC loop filtering skill is introduced Art, removes the blocking artifact in reconstruction image.Newest HEVC standard, there is two Video post-processing technologies, and one is deblocking effect It should filter（Deblocking Filtering, DBF）Technology, another is the adaptive migration technology of pixel（Sample Adaptive Offset, SAO）, the quality for improving reconstruction image.Blocking effect is generally present in predicted boundary or conversion On border, when DBF determines whether the border filters and filter according to coding mode, quantization parameter size and residual error coefficient situation Intensity operated accordingly, reach the operation of smoothed image.DBF energy in the case of the computation complexity of increase encoding and decoding end Enough effectively improve the subjective and objective quality of video.

Following examples, will respectively：Determine DBF possibility filtering boundary, determine that BS values, filtering strength adjudicate three sides Face is illustrated as follows：

First, DBF possibility filtering boundary is determined：

Prediction block in image block is obtained, above-mentioned prediction block refers to that an image block is divided into one or more image list Member；Square image block of the image block as shown in Figure 1A -1, the two horizontal rectangle prediction blocks of prediction block as shown in fig. 1 a-2；Figure It is that image block is divided into two prediction blocks shown in 1A-2, image block, which is divided into how many prediction blocks, arbitrarily to be set, this hair Bright embodiment is refused to limit；

2nd, BS values are determined：

BS values are determined the embodiments of the invention provide two kinds of alternative plans, Fig. 2 and Fig. 3 is please referred to respectively.

Alternative A, refers to Fig. 2：

For the sake of for convenience of description, it is assumed that the image block on the vertical boundary left side is P, and the image block on the right is Q or horizontal sides The following image block in boundary is P, and the image block of top is Q；So, in DBF, boundary intensity BS represents to be in the P on border both sides With Q lofty degree, the value is bigger, and the drop for representing border pixel values is bigger.BS is used to judge whether border filters and filter When filter strength power, therefore, the determination of BS values is a very important link in DBF.The volume of border both sides image block Code information can reflect the size of border drop.Above-mentioned coding information includes correspondence Primary layer（Lower level）The coding of prediction block Pattern information, can also include quantization parameter mark, can also include reference image information and motion vector.Above-mentioned quantization system Number mark indicates image block whether there is quantization parameter.Above-mentioned reference image information includes reference picture prediction direction and reference picture rope Draw.Above-mentioned reference picture prediction direction can be divided into forward prediction, back forecast and bi-directional predicted.Above-mentioned reference picture index is indicated Position of the reference picture in reference picture list.Above-mentioned motion vector represents that current block is relative with same block of locations in reference picture Motion excursion, each motion vector include horizontal direction component x and vertical direction component y.It is relative with it is same in reference picture Block of locations, it is referred to as static when the horizontal and vertical component of motion vector is not all offset.The coding mode of above-mentioned image block is exactly Image block in prediction by the way of, including Intra patterns, BaseLayer patterns and Inter patterns.Above-mentioned Intra patterns Refer to the coding mode being predicted using the adjacent pixel of present image block space.Above-mentioned BaseLayer patterns refer to utilize Primary layer（Lower level）The coding mode that same location drawing picture after up-sampling is predicted.When above-mentioned Inter patterns refer to utilize Between the coding mode that is predicted of image on domain.

Compared with HEVC, BaseLayer patterns are added in SHVC enhancement layer, the pattern is by Primary layer（It is relatively low Layer）Picture up-sampling after, be predicted using the elementary area of same position as reference unit, Inter patterns are with the time The elementary area in domain is predicted as reference unit.Compared with the reference unit of Intra pattern formations, BaseLayer patterns Nature collection image is more nearly with the reference picture of Inter patterns, with stronger predictive ability.Experiment is proved The residual error of BaseLayer patterns is more efficient according to the residual coding of Inter patterns.In a word, from the generation type of reference unit And substantial amounts of experimental data is drawn, the predictive ability of BaseLayer patterns is close to Inter patterns, and therefore, the present invention is implemented Example divides BaseLayer patterns and Inter patterns into class processing in BS decision processes.If in addition, boundaries on either side image The pattern of block is all BaseLayer patterns, and both quantization parameters are all 0（I.e.：There is no quantization parameter）, represent boundaries on either side Image block prediction both be from Primary layer, again without quantization parameter after prediction, with larger prediction similitude, be not likely to produce side Boundary's effect, therefore, in this case, the embodiment of the present invention is without filtering.DBF process tool is described by taking image block as an example Body, referring to Fig. 2, as follows：

This part is the introduction on carrying out BS calculating to the border that may be filtered.For the sake of description is convenient, definition is hung down The image block on the straight boundary left side is P, and the image block on the right is Q or the following image block of horizontal boundary is P, the image block of top For Q.BS is set to the first boundary intensity, the second boundary intensity and the 3rd boundary intensity and corresponds to BS=0, BS=1, BS=2 respectively. Without filtering during BS in the present embodiment=0.Above-mentioned coding mode is assigned for the reference picture of the image block of BaseLayer patterns Value refers to the index for specifying the reference picture of BaseLayer mode image blocks, and the present embodiment specifies BaseLayer mode image blocks Reference picture index be present image index.To motion arrow of the above-mentioned coding mode for the image block of BaseLayer patterns Amount is assigned static corresponding parameter and referred to the horizontal motion components of the motion vector of the image block of BaseLayer patterns and vertical fortune The value of dynamic component is all appointed as 0.

First, P and Q coding information, including coding mode are obtained, quantifies mark, reference picture and motion vector.

If the coding mode Intra patterns of at least one in P or Q, BS values are determined according to predictive mode.This feelings Condition shows that P or Q residual error may be larger, entered and larger boundary effect is easily produced after quantization operation, BS is set as 2.

If in the case where P and Q are not Intra pattern-coding patterns, when the coding of at least one in P or Q When pattern is BaseLayer patterns, BS values are determined according to predictive mode, quantization parameter and movable information.Such case show P and Q is BaseLayer patterns or one is BaseLayer patterns, and another is Inter patterns.When P and Q are BaseLayer patterns and when all not having quantization parameter（There is 0 quantization parameter in other words）, show that P and Q have similar prediction source And prediction effect, boundary effect is not likely to produce, BS is set as 0.It is BaseLayer patterns when one, another is Inter patterns When, the preceding predictive ability for having addressed BaseLayer patterns and Inter patterns quite and is better than the predictive abilities of Intra patterns, such as Fruit P and Q all without quantization parameter and with identical reference picture and with smaller difference motion vector, then BS be set as 0； Otherwise it is set as 1.The above-mentioned motion vector with smaller difference refers to that the x-component of motion vector and the absolute value of y-component are less than 4。

If P and Q are Inter patterns, BS values are mainly determined according to movable information and quantization parameter.When P or Q have During quantization parameter, it is understood that there may be weaker boundary effect, it is 1 to set BS.Else if when P and Q have different reference pictures, if It is 1 to put BS.Or the x-component of their motion vector（Y-component）Absolute value be more than or equal to 4, set BS be 1.Otherwise, P and Q In all no quantization coefficient, with identical reference picture, in the case of the motion vector with smaller difference, border is not likely to produce Effect, BS is 0.
