An efficient compression scheme based on adaptive thresholding in wavelet domain using particle swarm optimization

作者：

Highlights：

• An evolutionary optimization technique is devised for thresholding the wavelet coefficients.

• PSO is used to find the optimum thresholds for various sub-bands in the wavelet domain.

• The method is adaptive in the sense that a single threshold is not used for all sub-bands.

• A VLC coding scheme is used to efficiently compress the wavelet coefficients.
