Compression for JPEG-LS is generally slightlyworsethan JPEG 2000, but this highly depends on the image content. Decompression for JPEG-LS is generally much faster than JPEG 2000, but this depends on the exact softwaredecoderimplementations. This statement is valid for open-source implementations. 赞...
