摘要： The invention is related to lossless compression of prefix-suffix-codes wherein a prefix comprises unary code, and to corresponding decompression. The method for lossless compressing prefix-suffix-codes comprises the steps of forming a first contiguous bit sequence from the prefixes, and lossless compressing the first contiguous bit sequence by removing redundancy related to the difference between the first value's frequency in the first contiguous bit sequence and the second value's frequency in the first contiguous bit sequence. Bit values are unevenly distributed in the prefixes while distribution of bit values in the suffixes is more even. Therefore, better compression is achievable if the prefixes are compressed separately.
摘要翻译：本发明涉及前缀 - 后缀码的无损压缩，其中前缀包括一元码，并且与相应的解压缩相关。用于无损压缩前缀 - 后缀码的方法包括从前缀形成第一连续比特序列的步骤，并且通过去除与第一连续比特序列中的第一值的频率之间的差异相关的冗余来对第一连续比特序列进行无损压缩以及第一个连续比特序列中的第二个值的频率。位值不均匀分布在前缀中，而后缀中的位值分布更均匀。因此，如果前缀被单独压缩，则可以实现更好的压缩。

摘要： In known image compression, following quantisation, a very sparse distribution of significant (i.e. non-zero) amplitude coefficients of the transformed image signal may be obtained while most quantised coefficients are zeros. A costly task for a transform-based image compression in terms of resulting overall data rate is to record the locations of such significant coefficients within the coding blocks. In quartation processing, a ‘significant square’ (containing at least one non-zero amplitude coefficient in the coefficient block) is recursively divided into four smaller squares until single significant coefficients are reached, and the significance statuses of all generated squares are encoded. However, for some distribution patterns encoding the x-y-coordinates of the significant coefficients as binary numbers will lead to less coding cost. According to the invention, at least four different pattern determination or encoding modes are checked, and the encoding side selects the least costly one of these modes and transfers the corresponding mode information to the decoding side for corresponding decoding.
摘要翻译：在已知的图像压缩中，在量化之后，可以获得变换图像信号的显着（即非零）振幅系数的非常稀疏的分布，而大多数量化的系数是零。在所得到的总体数据速率方面，用于基于变换的图像压缩的昂贵任务是记录这些重要系数在编码块内的位置。在四次分组处理中，将“显着平方”（包含系数块中的至少一个非零幅度系数）递归地划分为四个较小的正方形，直到达到单个有效系数，并且编码所有生成的正方形的显着状态。然而，对于将有效系数的x-y坐标编码为二进制数的一些分布模式将导致较少的编码成本。根据本发明，检查至少四种不同的图案确定或编码模式，并且编码方选择这些模式中最便宜的一种模式，并将相应的模式信息传送到解码端用于相应的解码。

摘要： The invention is related to a method and a device for encoding of a bit sequence. Said method comprises generating, for each run of Ones comprised in the bit sequence, a unary representation of length of the respective run of Ones, generating a first sequence by concatenating the generated unary representations of lengths of runs of Ones, generating, for each run of Zeroes comprised in the bit sequence, a unary representation of the length of the respective run of Zeroes, generating a second sequence by concatenating the generated unary representations of lengths of runs of Zeroes, and bit plane encoding the generated first and second sequence of unary representations. In most cases, overall entropy of bit planes of unary representations of run lengths is smaller than entropy of the bit sequence. Thus, more compact encoding can be achieved.

摘要： A method for encoding a sequence of integers includes identifying a contiguous sub-sequence in the sequence of integers wherein the sub-sequence includes interrelated integers having a same prefix when being variable length encoded and an independent last integer. A code for the contiguous sub-sequence is formed using a code for an indication of the number of interrelated integers in the contiguous subsequence, a code of a prefix indication, and the suffixes of variable length codes of the integers in the contiguous sub-sequence. In doing so, a single prefix is sufficient instead of n individual prefixes.
