19th IEEE International Conference on Image Processing (ICIP)
作者: Zha, Shengxin Pappas, Thrasyvoulos N. Neuhoff, David L. Northwestern Univ Dept EECS Evanston IL 60208 USA Univ Michigan Dept EECS Ann Arbor MI 48109 USA
We propose a hierarchical lossy bilevel image compression method that relies on adaptive cutset sampling (along lines of a rectangular grid with variable block size) and Markov Random Field based reconstruction. It is... 详细信息
