Abstract
In order to apply the Human Visual System (HVS) model to JPEG2000 standard, several implementation alternatives are discussed and a new scheme of visual optimization is introduced with modifying the slope of rate-distortion. The novelty is that the method of visual weighting is not lifting the coefficients in wavelet domain, but is complemented by code stream organization. It remains all the features of Embedded Block Coding with Optimized Truncation (EBCOT) such as resolution progressive, good robust for error bit spread and compatibility of lossless compression. Well performed than other methods, it keeps the shortest standard code-stream and decompression time and owns the ability of VIsual Progressive (VIP) coding.
