Paper Abstract

The discrete wavelet transform is incorporated into the JPEG baseline coder for image coding. The discrete cosine transform is replaced by an association of two-channel filter banks connected hierarchically. The scanning and quantization schemes are devised and the entropy coder used is exactly the same as used in JPEG. The result is a still image coder that outperforms JPEG while retaining its simplicity and most of its existing building blocks. Objective results and reconstructed images are presented.
