Novel Bi-Orthogonal Filter Coefficient Wavelet Transform for Image Compression

B. Sivachandra mahalingam, Pranav priyadarshi prince, Ganga Shankar kumar

This thesis implements the TDM method and presents performance results for orthogonal and biorthogonal wavelets using both periodic and symmetric extension techniques . Our results for symmetric extension indicate a slight performance advantage for biorthogonal wavelets (particularly for low frequency images); this advantage is significantly smaller than recently published results. Our analysis also demonstrates the importance of linear phase filters on image compression performance
