Adaptive Synthesis Filter Banks for Image Compression
The subject of this paper is the design of adaptive synthesis filter bank for enhancement of image reconstruction by exploiting the phase diversity of synthesis filters in subband coding system. This paper for the first time, presents a comprehensive as well as an efficient approach of handling a large number of synthesis filters and reducing the computation complexity of the synthesis filter bank. The synthesis section comprises of linear phase filters along with a set of delay filters, where each filter has different phase characteristics to encounter reconstruction error especially at object edges in image compression applications.
Keywords: Adaptive synthesis filter banks, reconstruction error, delay filters, phase characteristics.
