Color Image Enhancement Algorithm Based on Nonsubsampled Contourlet Transform

Abstract: In this paper, a color image enhancement algorithm combined DCT transform and nonsubsampled contourlet transform was proposed. Since the difference of subband characteristics of nonsubsampled contourlet transform, different enhancement algorithms were proposed to enhance the low frequency...
