33rd IEEE International Conference on Acoustics, Speech and Signal Processing
作者: Kau, Lih-Jen Lin, Yuan-Pei Natl Chiao Tung Univ Dept Elec & Control Engr Hsinchu Taiwan
Many coding methods are more efficient with certain types of images than others. In particular, run-length coding is very useful for coding areas of little changes. Adaptive predictive coding achieves high coding effi... 详细信息
