Abstract

This paper introduces a new image coder based on several different block transforms and on group testing. It extends the Group Testing for Wavelets algorithm [2] by replacing the discrete wavelet transform with the discrete cosine transform, and orthogonal and biorthogonal lapped transforms. In particular, we compare the performance of group testing on different block transforms, and show that on the standard Barbara image, the rate-distortion performance of the group testing on lapped biorthogonal transforms is significantly better than previous zerotree techniques based on the wavelet transform.
