Design and Application of Quasi-Orthogonal Filter Banks
Yu Hou, Xuesong Yin · Procedia Engineering · 2012
Based on the wavelet theory, a class of novel filter banks is designed and constructed. The filter banks have mathematical properties of finite impulse response, symmetry, linear phase, quasi-orthogonality, high regularity etc. As an application on signal and information processing, a number of image compression experiments are performed on four testing images with five different bit rates. Peak signal-to-noise ratio and structural similarity index measure are used to evaluate the image quality. The experimental results show that the proposed filter banks have a very good performance of image compression.
