Abstract

The discrete wavelet transform has recently emerged as a powerful technique for decomposing images into various multi-resolution approximations. Multi-resolution decomposition schemes have proven to be very effective for high-quality, low bit-rate image coding. In this work, we investigate the use of entropy-constrained trellis coded quantization for encoding the wavelet coefficients of both monochrome and color images. Excellent peak signal-to-noise ratios are obtained for encoding monochrome and color versions of the 512×512 `Lenna' Image. Comparisons with other results from the literature reveal that the proposed wavelet coder is quite competitive.
