Abstract
The report gives results under the Core Experiment on Filter Banks and Wavelets. The motivation behind this work is to test different filter banks/wavelet transforms and decomposition types for a number of images and bit rates. In order to assess decoded image quality we include four different error criteria. An informal subjective comparison test is also conducted. The baseline coder with the recommended options for different images and bit rates given by the software provider is included for the sake of completeness. Although such comparisons with the baseline system may be unfair. The following conclusions are drawn. A combination of 8-channel, 32-tap uniform parallel and gain optimized 9/7 tree-structured filter banks (System A) gave the best average results both in terms of objective error criteria and subjective assessments. The gain optimized 9/7 filter bank performed better than the wavelet 9/7 and it particularly had less ringing artifacts. For texture images the proposed (gai...
