Abstract:
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.
