语法信息的二值化编码处理方法及装置 Binarization processing method and apparatus coding syntax information

技术领域 FIELD

[0001] 本发明涉及通信技术,尤其涉及一种语法信息的二值化编码处理方法及装置。 [0001] The present invention relates to communication technology, particularly to a syntax information encoding binarization processing method and apparatus.

背景技术 Background technique

[0002] 当前基于块的视频编码混合框架中通常包括预测模块、变换模块、量化模块和熵编码模块。 [0002] Current video coding framework based on hybrid block typically includes a prediction module, the transform module, the quantization module and an entropy encoding module. 其中,预测模块用于编码端获得视频序列编码图像的图像块的预测块信息,进而得到图像块的残差,预测补偿模块用于解码端获得当前解码图像块的预测块信息,再根据解码得到的图像块残差获得当前解码图像块。 Wherein the prediction means for obtaining a prediction block encoding side information image block sequence encoding a video image, and thus to obtain the prediction residual block information, block prediction image compensation module for decoding to obtain the current decoded image block end, and then obtained according to the decoding a residual image block to obtain the decoded image of the current block. 预测模块通常包含帧内预测和帧间预测两种技术。 Prediction module typically comprise intra prediction and inter prediction two techniques. 其中,帧内预测技术利用当前图像块的空间像素信息去除当前图像块的冗余信息以获得残差;帧间预测技术利用当前图像邻近的已编码或已解码图像像素信息去除当前图像块的冗余信息以获得残差。 Wherein the intra prediction techniques using the current image block of spatial pixel information to remove redundant information of the current image block to obtain a residual; interframe prediction technique using the current image adjacent to the image coded or decoded pixel information of the current block redundancy is removed over information to obtain residuals. 而帧内预测技术或帧间预测技术又分别存在着多种编码预测模式以供选择,具体选择哪一种编码预测模式进行编码解码则是通过计算结果来确定。 And an inter prediction or intra prediction techniques and technologies are a variety of encoding the prediction modes exist for selection, which specific coding prediction mode selected for encoding and decoding is determined by calculation.

[0003] 为了能标识出类似如编解码过程中每个编码单元具体选择了哪一种编码预测模式进行处理的语法信息,在编码过程中,需要对每个编码单元的编码预测模式的语法信息进行熵编码处理。 [0003] In order to identify syntax information such as the encoding and decoding process is similar to each coding unit which specifically selected prediction mode encoding process in the encoding process, syntax information required for encoding the prediction mode for each encoding unit entropy encoding process. 由于熵编码处理目的在于去除信息的统计冗余,因此在对这些语法信息进行二进制化过程中,合理的二值化处理方式能有效提高编码效率和降低编码复杂度。 Since the entropy coding process is to remove statistical redundancy object information, and therefore some of the syntax information during binarization, binarization rational approach can effectively improve coding efficiency and reduce the coding complexity.

[0004] 现有技术中,对于语法信息进行二值化过程,一般采用两种方式:一种是对语法信息直接进行定长式二值化,即语法信息都采用相同位长的二值化方式;另一种是在编码前已经确定了语法信息二值化编解码策略。 [0004] In the prior art, for binarizing the syntax information process, generally used in two ways: one is directly syntax information fixed-length binary type, i.e. use the same syntax information bit length binarized manner; the other is determined before encoding the syntax information has been binarized codec strategy.

[0005] 但是,采用现有技术不能很好的消除信息冗余性。 [0005] However, with the prior art are not well eliminate redundancy information.

[0040] 图1为本发明提供的语法信息的二值化编码处理方法实施例一的流程示意图,如图1所示,该方法包括: Encoding a schematic flow binarization processing method [0040] FIG 1 provides the syntax information of a present embodiment of the invention, shown in Figure 1, the method comprising:

[0041] S101、采用初始二值化编码策略对语法信息集合中的各语法元素进行第一二值化,获取各语法元素对应的第一二值化字符串(本发明中称为bin串)。 [0041] S101, using the initial coding strategy binarized syntax element syntax information for each set a first binarizing respective syntax element corresponding to obtain first binary strings (herein referred to as the present bin string) . 各语法元素对应的bin串不全相同。 Each bin of the syntax element corresponding to the same string failure. 其中,二值化可以采用各种二元码,例如:哈夫曼(Huffman)码、一元码、一元截断码、指数哥伦布码和可配置变长码等,或不同二元码的组合。 Wherein, binarization may be employed various binary code, for example: Huffman (Huffman) codes unary code, a dollar truncation symbols, and exponential Golomb code can be configured to variable length code, etc., or a combination of different binary codes.

[0042] 初始二值化编码策略可以采用现有技术进行设置,也可以根据实验统计测试数据经验获得。 [0042] The initial binary coding strategy can be employed to set the prior art, can also be obtained according to experimental data empirical statistical tests.

[0043] 视频编码过程中,会不断地、多次地对上述语法信息中的各语法元素进行二值化。 [0043] The video encoding process, will continue, a plurality of times for each syntax element above syntax information is binarized. [0044] S102、根据上述初始二值化编码策略确定是否执行编码模式分布统计和更新二值化编码策略。 [0044] S102, based on the initial binary coding strategy determining whether to perform coding mode distribution statistics and updating binary coding strategy. 若是,则执行S103,若否,则执行S104。 If yes, S103, and if not, perform S104.

[0045] S103、采用更新后的二值化编码策略对上述语法信息集合中的各语法元素进行第二二值化,获取各语法元素对应的第二二值化字符串。 [0045] S103, the binarized using the updated coding strategy for each syntax element above syntax information set in the second binarized syntax element corresponding to each acquire a second binary string. 同样,二值化可以采用各种二元码,例如:Huffman码、一元码、一元截断码、指数哥伦布码和可配置变长码等,或不同二元码的组合。 Also, binarization may be employed various binary code, for example: Huffman codes unary code, a dollar truncation symbols, and exponential Golomb code can be configured to variable length code, etc., or a combination of different binary codes.

[0046] S104、采用上述初始二值化编码策略对上述语法信息集合中的各语法元素进行第二二值化,获取各语法元素对应的第二二值化字符串。 [0046] S104, the above-described initial binary coding strategy for each syntax element above syntax information set in the second binarized syntax element corresponding to each acquire a second binary string.

[0047] 本实施例中,根据初始二值化编码策略确定是否执行编码模式分布统计和更新二值化编码策略,进而采用更新后的二值化编码策略或出示二值化编码策略来进行二值化,实现了可以根据实际情况灵活地选择二值化编码策略,特别是可以根据编码模式分布统计结果制定二值化编码策略,有助于更好地消除信息冗余,避免了固定采用一种二值化编码策略而造成信息冗余的问题。 [0047] In this embodiment, it is determined whether to perform coding mode distribution statistics and updating binary coding strategy the initial binary coding strategy, and further using binary coding strategy or to produce binarization coding strategies to two updated value, realize the flexibility to choose the binary coding strategy based on the actual situation, in particular, can be distributed according to the encoding mode statistics to develop the binary coding strategy, contribute to better eliminate redundant information, avoiding the use of a fixed kind of binary coded information redundancy strategy caused problems.

[0048] 图2为本发明提供的语法信息的二值化编码处理方法实施例二的流程示意图,上述执行编码模式分布统计和更新二值化编码策略的具体步骤为: Specific Example II Step schematic flow chart coding binarization processing method [0048] FIG. 2 provides the syntax information of the embodiment of the present invention, the above-described encoding is performed and update the statistical distribution mode binarization coding strategy is:

[0049] S201、对上述语法集合中的各语法元素二值化编码策略所需的总比特(bit)数进行分布统计,获取分布统计结果。 [0049] S201, the respective syntax element above syntax set encoding the desired policy binarized total bit (bit) number for distribution statistics, acquiring distribution statistics. 其中,总bit数为二值化过程中用于标识语法信息集合中各语法元素的bit数大小。 Wherein the total number of bit binarization process for each syntax element bit operand size set identifier syntax information.

[0050] S202、根据分布统计结果制定更新二值化编码策略。 [0050] S202, based on the statistical distribution of the results of the development of the binary update encoding strategy.

[0051] 具体为,采用该语法信息集合中的各语法元素的二值化编码策略所需的总bit数最小化,制定更新二值化编码策略。 [0051] Specifically, the total number of bit values ​​encoding the desired policy syntax element using the syntax information of each set of two minimization, binary coded develop updated policy. 举例说明,例如:一个语法集合T= {aj,i=0,l……M,M为自然数,表示语法信息集`合T所取值的个数,假设M=6,二值化各语法元素的次数为{4,3,3,I, 1,2},则采用总bit数最小化对应的二值化编码策略进行二值化,其语法信息集合中各语法元素的bit数大小为{00,01,10,1110,1111,110},所需总bit数为4*2+2*3+2*3+1*4+1*4+2*3=34。 Exemplified, for example: a syntax set T = {aj, i = 0, l ...... M, M is a natural number and represents the number of syntax information set by the value of T 'together, assuming M = 6, each of the binarized syntax is the number of elements {4,3,3, I, 1,2}, using the binary coding strategies to minimize the total bit number of the corresponding binarized, the number of bit size of each syntax element for syntax information sets 00,01,10,1110,1111,110 {}, the required total number of bit 4 + 2 * 3 * 2 * 2 + 3 + 4 * 1 + 1 * 4 + 2 * 3 = 34. 而如果采用定长二值化策略(3bit)进行二值化,其语法信息集合中各语法元素的bit数大小为{000,001,010,011,100, 101},所需总bit数为3* (4+3+3+1+1+2) =42,可以看出采用定长二值化方式会造成位的浪费。 If using a fixed-length binary strategy (3bit) is binarized, the number of bit sizes of the syntax element is a syntax information sets {000,001,010,011,100, 101}, the total number of bit required for the 3 * (3 + 4 + 3 + 1 + 1 + 2) = 42, it can be seen using fixed-length binary bit mode will cause waste.

[0052] 需要说明的是,上述执行编码模式分布统计和更新二值化编码策略可以是执行周期或非周期的编码模式分布统计和更新二值化编码策略。 [0052] Note that the encoding is performed and update the statistical distribution mode binarized encoding strategy may be a coding mode for carrying out periodic or aperiodic distribution statistics and updating binary coding strategy.

[0053] 进一步地,上述根据初始二值化编码策略确定是否执行编码模式分布统计和更新二值化编码策略,具体为:判断初始二值化编码策略是否为基于上述编码模式分布统计和更新二值化编码策略的二值化编码策略,即判断初始二值化编码策略是否为基于图2所示实施例的二值化编码策略;若是,则可以选择执行或不执行上述编码模式分布统计和更新二值化编码策略,若选择不执行,就继续采用初始二值化编码策略对语法信息集合中的各语法元素进行二值化,选择执行,那就在执行之后采用更新后的二值化编码策略对语法信息集合中的各语法元素进行二值化;若否,则执行上述编码模式分布统计和更新二值化编码策略的二值化编码策略。 [0053] Further, the determining whether to perform coding mode distribution statistics and updating binary coding strategy the initial binary coding strategy, specifically: determining an initial binary coding strategy whether distribution statistics and updated based on the encoding mode two binary coding strategy binary coding strategy, i.e., an initial determination whether the binary coding strategy based on binary coding strategies embodiment shown in FIG. 2; if yes, may be selected or may not perform distribution statistics and the encoding mode update the binary coding strategy, if you choose not to perform, we continue to use the binary coded initial strategy for each syntax element syntax information collection binarization, select Run, then using the binary updated after execution coding strategy for each syntax element syntax information set in binarizing; if no, the coding mode distribution statistics and updating binary coding strategy binarization coding strategy. 具体实施过程中,可以根据编码的复杂度情况决定是否执行编码模式分布统计和更新二值化编码策略,一般情况下,如果编码的复杂度低时,可以选择不执行。 Specific implementation, the complexity of the situation can be determined according to whether the coding distribution statistics and updating binary coded coding mode execution policy, in general, if the low complexity of the encoder may choose not to perform. [0054] 具体实施过程中,上述二值化编码策略具体可以为定长二值化编码策略,和/或,变长二值化编码策略。 [0054] The specific implementation process, when the binary coding strategy may be particularly fixed-length binary coding strategy, and / or variable-length binary coding strategy.

[0055] 需要说明的是,在编码过程中,还可以周期性或非周期性的对二值化编码策略进行标识。 [0055] Incidentally, in the encoding process, it may be periodic or aperiodic binarized coding strategies are identified.

[0056] 采用对视频编码过程中某语法信息进行编码,举例说明上述实施例,假设该语法信息集合中包括7个语法元素{A、B、C、D、E、F、G},其初始二值化编码策略采用定长二值化编码策略,生成的bin串需要3bit位,如表I所示, [0056] The use of a syntax information a video encoding process for encoding, illustrate the above-described embodiment, it is assumed that the syntax information included in the set 7 syntax elements {A, B, C, D, E, F, G}, initial binary coding strategy employed bin string fixed length binary coding strategy, the need to generate 3bit bit, as shown in table I,

[0057]表 I [0057] TABLE I

[0058] [0058]

Figure CN103391440AD00081

[0059] 由于该初始二值化编码策略并不是基于编码模式分布统计和更新二值化编码策略的二值化编码策略,因此,先对该语法信息集合中的各语法元素的二值化编码策略所需的总比特数进行分布统计,获取分布统计结果,由统计结果确定更新二值化编码策略,其中是由语法信息集合中的各语法元素的二值化编码策略所需的总bit数最小化来决定更新二值化编码策略的。 [0059] Since the initial encoding of binary distribution strategy is not based on statistical coding mode and update the binary coding strategy binarization coding strategy, therefore, the two first binary code of each syntax element syntax information collection total number of the total number of bits required bit strategy distribution statistics, acquiring distribution statistics, determining an updated binarization result by the statistical coding strategy, which is a syntax element of each of the two set of syntax information encoding the desired value of the strategy minimizing decided to update the binary coding strategy. 假设采用更新后的二值化编码策略生成的bin串如表2所示, Assuming binary coding strategy updated bin string generated as shown in Table 2,
