Subband Image Coding Using Cosine Modulated Filter Banks with Perfect Reconstruction and Linear Phase

11 years 4 months ago
Subband Image Coding Using Cosine Modulated Filter Banks with Perfect Reconstruction and Linear Phase
lye propose a lossy image coding scheme based on the recently introduced even-stacked cosine modulated filter banks (CSIFBs) that allow linear phase filters in all channels. We describe modifications of the JPEG quantization matrix and zig-zag sequence to match the structure of even-stacked CSIFBs. and we discuss the efficient design of even-stacked CSIFBs. The rate-distortion performance and perceptual performance of the proposed transform coder are demonstrated using simulation results.
