一种小波变换的小波系数均衡图像增强算法

摘要

介绍了几种经典的图像增强算法,依据经典直方图均衡化算法思想,提出了在小波变换下的小波系数均衡化图像增强算法,并给出了计算步骤.与经典直方图均衡化算法、同态滤波实验结果相比较,表明提出的算法可有效增强图像、抑制噪声.%Several image enhancement algorithms are introduced. According to the classical histogram equalizing algorithm, a wavelet coefficients e qualizing image enhancement algorithm is proposed based on the wavelet transform, and computation steps are given. The proposed algorithm in this pa per is compared with the homomorphism filter and the classical histogram equalization. Experimental results indicate that the new algorithm in this paper can enhance image and eliminate noise efficiently.
