Abstract:	This study addresses the design of an adaptive dynamic range compression algorithm for color image enhancement. To achieve this purpose, a novel image-dependent nonlinear intensity-transfer function is first proposed to produce a satisfactory dynamic-range compression result with less color artifacts. The proposed algorithm is then derived by combining the proposed adaptive nonlinear intensity-transfer function with an efficient local contrast enhancement algorithm. Experimental results validate that the proposed method provides better visual representation in comparison with an existing color image enhancement method.
