Hello, have you found these items from URL: & quot; http://www.cipr.rpi.edu/research/SPIHT" . This set of programs are included in this distributed activity, including the demonstration version SPIHT source written in MATLAB language. Just like writing, single. You can use this package: compress & quot; image_ name.raw" , 1 byte pixel, r line, column pair CR bit / pixel. For example: compression is named 'compression' goldy.raw , 512 x 720 gray 8-bit image (Height x width) to 0.50 BPP. > mSpiht_ N (\'goldy \ ', [512720], 0.5)% normal view and gray color & gt; mspiht_ N (\'bike \ ', [512720], 0.5,' N3 ')% warm colors and views & gt; msphit_ n (\'image_ Name \ ', [R, C], Cr & lt;, \'aspect colormap \' & gt;) the number of braces is optional R: the number of image rows (height) C: the number of image columns (width) (default = R) Cr: bit aspect ratio per pixel mapping (optional) compression ratio: default aspect ratio fixed image size and default mapping is original gray. Different view colors are provided. To change the color in view mode, just enter a number from 1 (gray) to 5 (Orange). The default value is 1 (gray). For the stretch view, enter 'n', (optional) and 'NN',, where n is a number. Thank you very much
