IEEE International Symposium on Circuits and Systems (ISCAS)
作者: N. Memon V. Sippy Xiaolin Wu Northern Illinois University USA University of Western Ontario Canada
It has long been realized that the current JPEG standard does not provide state-of-the-art performance in its lossless mode. In view of this, the International Standards Organization (ISO) recently solicited proposals... 详细信息

International Conference on Digital Signal Processing (DSP)
作者: G. Lafruit Y. Andreopoulos B. Masschelein IMEC v.z.w. DESICS Belgium Vrije Universiteit Brussel Brussels Belgium
In JPEG2000, the wavelet transformed image is subdivided into equally sized data blocks, which are independently entropy coded. It is therefore often strongly suggested that these blocks can be decoded on the instant ... 详细信息
