A method is presented for encodins memoryless sources using trellis coded quantization(TCQ). The trellis symbols are entropy-coded using arithmetic coding. We also present a rnodification of the codebook which resuls in improved rate-distortion performance at low bit rates. The arithmetic and trellis coding method is used for encoding wavelet transform image. The proposed method the performance of the arithmetic coded TCQ for wavelet transform image has better rate-distortion performance compared with JPEG. uniform threshold quantization and finite state scalar quantization.
