Efficient shape modeling:: ε-entropy, adaptive coding, and boundary curves -vs- blum's medial axis
收藏 引用
INTERNATIONAL JOURNAL OF COMPUTER VISION 2007年 第2期74卷 183-199页
作者: Leonard, Kathryn CALTECH Dept Appl & Computat Math Pasadena CA 91125 USA
We propose efficiency of representation as a criterion for evaluating shape models, then apply this criterion to compare the boundary curve representation with the medial axis. We estimate the epsilon-entropy of two c... 详细信息
