Abstract: The present invention provides an image compression method and device. When a coding block is coded, first, second and third reconstructed reference pixel sample sets, of which position labels are not intersected, are searched to obtain one or more optimal fixed-width variable-length pixel sample matching strings according to a preset evaluation criterion. Each matching string is represented by a matching distance and a matching length. For a sample of which a match is not found, a pseudo matching sample is calculated from an adjacent sample. Matching string searching may be performed in a pixel component plane only, and may also be performed in a three-component individually intersected pixel space in a packed format. Optional quantization or transformation-quantization coding, predictive coding, differential coding and entropy coding are further executed on the matching distance, the matching length and a matching residual. Multiple sample division manners and arrangement manners may be adopted for matching, and optimal ones are selected from them. For the same Coding Unit (CU), conventional-prediction-based hybrid coding is simultaneously performed, and an optimal result is selected finally.

Abstract translation: 本发明提供一种图像压缩方法和装置。 当对编码块进行编码时，搜索位置标签不相交的第一，第二和第三重建参考像素样本集合，以根据预设的评估标准获得一个或多个最优固定宽度可变长度像素样本匹配串 。 每个匹配的字符串由匹配的距离和匹配的长度表示。 对于未找到匹配的样本，从相邻样本计算伪匹配样本。 匹配字符串搜索可以仅在像素分量平面中执行，并且也可以以打包格式在三分量单独相交的像素空间中执行。 在匹配距离，匹配长度和匹配残差上进一步执行可选量化或变换量化编码，预测编码，差分编码和熵编码。 可以采用多种样本划分方式和排列方式进行匹配，从中选出最佳选择方式。 对于相同的编码单元（CU），同时执行基于常规预测的混合编码，最终选择最佳结果。
