An improved algorithm of histogram equalization for image enhancement is discussed. After the image containing noises was wavelets transformed, the low frequency wavelet coefficients are equalized, and then all the wavelets are inverse transformed to enhance the image. This improved algorithm of histogram equalization gets a better image enhancement effect by test verification.
讨论了一种用于图像增强的改进直方图均衡算法。对含噪图像进行小波变换后，对低频小波系数进行均衡处理，然后对所有小波进行逆变换以增强图像。经测试验证，这种改进的直方图均衡算法获得了更好的图像增强效果。
