Because of the higher resolution, the data volume of remote sensing image is very large. To communicate and use them on network, efficient compression is very important. Based on the frame of conventional JPEG2000 compression, this paper puts forward a kind of modified compression algorithm aiming at characteristics that the correlation of remote sensing image is lower than common images. The core...
Based on the statistical analysis of relation between CBP (Coded Block Pattern), MVD (Motion Vector Difference) and each coding mode, a fast mode selection algorithm based on macroblock-adaptive is proposed. In this algorithm, adaptive judgment strategies are adopted to filter partial coding mode quickly. The residual CBP, MVD information is used adequately to identify the relativity of intra and...
This paper proposes an efficient two-description image coding technique. The two side descriptions of an image are generated by quincunx subsampling. The decoding from any side description is done by an interpolation process that exploits sample correlation. Although the quincunx subsampling is a natural choice for the best use of sample correlations in image multiple-description coding (MDC), each...
When wavelet transform is applied to image compression, the chosen wavelet base affects the efficiency of coding and the quality of the reconstructed image, because the property parameters of different wavelet bases are varied, it is very important to research the correlation between the wavelet base properties and image compression. Chosen wavelet bases of one family for the experiments are convenient...
