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.
