This paper proposes a novel low-complexity, efficient 9/7 wavelet filters implementation for image compression applications. The 9/7 wavelet filters are widely used in different image compression schemes, such as the JPEG2000 image coding standard. Thus the implementation of efficient codecs is of great concern. The performance of a hardware implementation of the 9/7 filter bank depends on the accuracy with which filter coefficients are represented. However the greatest part of current implementations consider filters taps as numbers to be implemented. The aim of this work is to show that great complexity reduction can be achieved going through the derivation of the 9/7 taps values.
