HEXAGONAL DISCRETE COSINE TRANSFORM FOR image-CODING
收藏 引用
ELECTRONICS LETTERS 1991年 第9期27卷 781-783页
作者: WU, HS Inst. of Image Processing & Pattern Recognition Shanghai Jiao Tong Univ. China
The discrete cosine transform plays an important role in rectangularly sampled image coding for its excellent performance in information compaction. Hexagonal sampling is the optimal sampling strategy for two-dimensio... 详细信息

Color-texture based unsupervised segmentation using JSEG with fuzzy connectedness
收藏 引用
Journal of Systems Engineering and Electronics 2006年 第1期17卷 213-219页
作者: Zheng Yuanjie Yang Jie Zhou Yue Wang Yuzhong Inst. of Image Processing and Pattern Recognition Shanghai Jiaotong Univ. Shanghai 200030 P. R. China
Color quantization is bound to lose spatial information of color distribution. If too much necessary spatial distribution information of color is lost in JSEG, it is difficult or even impossible for JSEG to segment im... 详细信息
