Paper Abstract

A new despeckling method based on matching pursuit of subband coherent structures of a wavelet-decomposed SAR image is suggested. The iterative pursuit of coherent structures within each subband is organized as an adaptive thresholding of wavelet coefficients using the best wavelet basis chosen from the library of bases minimizing the cost function. The processed image is formed as the cumulative sum of the pseudo images computed by applying of inverse wavelet transform within each iteration. The results of computer modeling have shown the superb quality of the enhanced images obtained by the proposed method in the sense of different criteria as MSE, PSNR, SSIM.
