基于小波域反正切变换的红外图像增强算法
Infrared Image Enhancement Algorithm Based on Arc-tangent Transform in Wavelet Domain
摘要
Abstract
Because of noise and low contrast of the infrared image, an infrared image enhancement algorithm is proposed. Evaluating function is constructed by combing information entropy, signal-noise-ratio with standard variance in order to evaluate the enhanced image quality. Thus, an efficient nonlinear transform function is designed by arc-tangent transform in stationary wavelet domain so as to enhance the contrast of an infrared image. The optimal nonlinear transform parameter is obtained by combing differential evolution algorithm with the constructed evaluating function. Experimental results show that the proposed algorithm can efficiently enhance the contrast of the infrared image while getting a good robust to noise in the infrared image.关键词
