LOSSLESS IMAGE COMPRESSION METHOD |
摘要 |
A compression method is used for processing an image having a plurality of pixels, in which an image width of the image is W. The compression method includes the steps of selecting N continuous pixels from the image, where N is a positive integer greater than or equal to 2 and is less than the image width W; performing differential pulse code modulation (DPCM) so as to obtain N non-negative differences corresponding to the N pixels according to values of the N pixels; calculating to obtain a coding parameter according to the N non-negative differences; and coding the N non-negative differences according to the coding parameter. |
