Analysis of coding performance improvement caused by frequency band partition in subband image coding using generalized gaussian distribution
Haruhiko Miyazaki, Masashi Kameda (Iwate Pref. Univ.) IE2013-27
Abstract (in Japanese) (See Japanese page) 
(in English) In subband image coding, the optimum frequency band partition which segments the 2-D frequency domain based on the power or kurtosis of subband signals has been proposed in order to improve the coding performance. However, the coding performances of both previous optimum frequency band partition methods have depended on the contents of input image and the coding rate. In this paper, new optimum frequency band partition is presented according to the distributions of subband signal resemble each other, after each subband signal is approximated by using the generalized gaussian distribution. It is clarified that the coding performance improvement in the optimum frequency band partition has the relationship with the classification for the distribution of subband signal.
