Progressive image coding using trellis coded quantization
In this work, we present coding techniques that enable progressive transmission when trellis coded quantization (TCQ) is applied to wavelet coefficients. A method for approximately inverting TCQ in the absence of least significant bits is developed. Results are presented using different rate allocation strategies and different entropy coders. The proposed wavelet-TCQ coder yields excellent codi...
متن کاملTurbo trellis coded modulation for transform domain distributed video coding
A transform domain distributed video coding (DVC) codec is proposed using turbo trellis coded modulation (TTCM). TTCM symbols are generated at the DVC decoder using the side information and the parity bits received from the DVC encoder. These generated symbols are used at the TTCM-based DVC decoder to decode the bit stream. Simulation results show that a significant rate-distortion performance ...
متن کاملUniversal trellis coded quantization
A new form of trellis coded quantization based on uniform quantization thresholds and "on-the-fly" quantizer training is presented. The universal trellis coded quantization (UTCQ) technique requires neither stored codebooks nor a computationally intense codebook design algorithm. Its performance is comparable with that of fully optimized entropy-constrained trellis coded quantization (ECTCQ) fo...
متن کاملEmbedded Trellis Coded Quantization
Embedded Trellis Coded Quantization (E-TCQ) is introduced as an embedded quantization technique which achieves good rate-distortion performance for reasonable computational complexity. The performance of E-TCQ is investigated for memoryless Gaussian, Laplacian, and uniform sources. E-TCQ is shown to outperform multi-stage TCQ. For Gaussian and Laplacian sources the performance of E-TCQ shows la...
متن کاملA low-delay transform domain approach to trellis coded quantization
In this paper we propose a new transform domain coding technique called transform trellis coded quantization (TTCQ) that is based on the trellis coded quantization technique recently proposed where Ungerboeck’s amplitude modulation trellises and set partitioning ideas are used for source coding. We combine the proposed technique with a transform domain formulation for small frame sizes obtainin...
