有没有人有关于JBIG2的源码。关于二值图象压缩的。找不到。
另外，有没有人做过关于scalable resolution压缩的工作？

What do you want? I may help you a little.
For lossless bi-level image, JBIG2 will be the best. For example, the
compression rate for the image "lena" provided by JBIG1 is about
0.1370bytes/pel. JBIG2 will provide an improvement for about 20%.
For lossless gray-scale image, CALIC and LOCO are the best ones so far.
LOCO will the core part for JPEG2000. I remember for image "lena", the result
provided by CALIC is about 2.99bits/pel. LOCO should definitely do better
than this.
For lossy gray-scale |
