Abstract :
This brief proposes a novel low-complexity, efficient 9/7 wavelet filters VLSI architecture for image compression applications. The performance of a hardware implementation of the 9/7 filter bank depends on the accuracy of coefficients representation. The aim of this work is to show that great complexity reduction with excellent performance can be achieved going through the derivation of the 9/7 taps values
