Embodiment Construction
[0052] The invention relates to a maximum error image compression method based on conversion compression, the algorithm can shorten compression time, improve image compression ratio and reconstruction quality. The present invention is achieved through the following technical solutions. First, the first level of row conversion compression is performed, and the generated approximation (mean value) and detail components (conversion coefficients) are stored accordingly; then the newly generated approximation part is subjected to the first level of column conversion compression, and the corresponding approximation and details are stored at the same time component; alternately perform next-level row and column conversion and compression on the newly generated approximation until only one approximation remains; finally, the approximation and detail components can be used for data reconstruction.
[0053] The specific technical scheme is as follows:
[0054] 1. The first level of row...
