摘要: Recently JPEG 2000 has adopted the integer wavelet to attain "lossless" coding of images. However existing DCT based "lossy" still prevails all over world. This paper focuses on which can perform maintaining compatibility coding. So far, we have optimized word length each multiplier in considering colored spectrum input image signal. it is remained unknown that 1) Is assigned robust change signal? 2) How does depend structure transform? report intended as an investigation theoretical analysis answer such questions.
