Shape-VQ-based lossless hybrid ADPCM/DCT coder
The discrete cosine transform (DCT) has been shown as an optimum encoder for sharp edges in an image (Andrew and Ogunbona, 1997). A conventional lossless coder employing differential pulse code modulation (DPCM) suffers from significant deficiencies in regions of discontinuity, because the simple model cannot capture the edge information. This problem can be partially solved by partitioning the...
متن کاملShape VQ-based adaptive predictive lossless image coder
A new shape adaptive predictive lossless image coder is proposed. Three classes of block shapes are delineated with associated “optimum” predctors. Each image is partitioned into sub-blocks that are classified into one of the three classes using vector quantisation. The encoder then employs the predictor corresponding to the class of the block under consideration. Performance evaluation of the ...
متن کاملA Nonlinear VQ-Based Predictive Lossless Image Coder
A new lossless predictive image coder is introduced and tested. The predictions are made with a nonlinear, vector quantizer based, adaptive predictor. The prediction errors are losslessly compressed with an arithmetic coder that presumes they are Laplacian distributed with variances that are estimated during the prediction process, as in the approach of Howard and Vitter. I . Introduction Predi...
متن کاملHybrid predictive/VQ lossless image coding
A multiplicative autoregressive model is used in a lossless predictive image coding scheme. The use of vector quantisation (VQ) for compression of the model coefficients leads to an improved compression ratio. Both image adaptive and universal codebooks are considered. A comparative analysis of the new coder is presented through simulation results.
متن کاملAn 800bps VQ Based LPC Voice Coder
The idea of applying vector quantization (VQ) to linear prediction coding (LPC) to realize a very low bit-rate speech coder with reasonable speech quality is investigated in this research. Instead of encoding LPC parameters directly, line spectral frequency (LSF) coefficients are obtained through a transformation of LPC and then encoded via VQ in the proposed scheme. In order to utilize the int...
