A new fast algorithm for the remote sensing image progressive compression was proposed. This algorithm has three embedded characters (resolution, region of interest, and fidelity), low computing complexity and favorable loss compression performance. Every resolution of wavelet transform coefficients were partitioned into many precincts according to the area. In each sub-band of each precinct, the...
A lossy compression scheme for Bayer images is proposed in this paper. Recently, it was found that compression-first schemes outperform the conventional demosaicking-first schemes in terms of output image quality. Balanced multiwavelet packet transforms effectively remove CFA image correlation between frequency bands. Wavelet coefficients shuffling exploring subband correlation makes it suitable for...
The DEM multi-scale representation, progressive compression and transmission based on integer lifting wavelet can eliminate the redundant data between resolutions for web-based spatial information system. Through experimental data and theoretical analysis, the 2/6 integer wavelet was found to be the most suitable transform for the DEM multi-scale progressive compression among the 14 reversible integer...
