Gray Compression of SAR Images Based on RMA
Pei Huang · Wuhan University Journal · 2003
According to the special principle of SAR(synthetic aperture radar) image display, and aiming at the problem in traditional gray compression methods that the outline of the original image's histogram cannot be well kept, the paper provides a new method of gray compression based on the theory of RMA(radiometric multiresolution analysis). The result of test on real SAR image shows that the new method is far superior in keeping the outline of the image’s histogram than that of traditional methods.
