【Abstract】 Put forward an effective compressing method for remote sensing image. Firstly, the image is (decomposed) by biorthogonal wavelet transformation, and then the wavelet coefficients are vector quantized. Codebook of vector quantization is designed with genetic annealing algorithm. The satisfied experimental results are obtained. It is indicated that this algorithm can speed up the encoding process and improve (reconstructed) quality of image.更多还原
