    According to the characteristics of some gray images such as low resolution and contrast,high noise and poor visual characteristics,a new image enhancement method based on wavelet transform and histogram equalization is proposed. The characteristics of wavelet transform such as multi-scale and multi-resolution are incorporated with histogram equalization method in the method,and assisted with median filter de-noising and homomorphism filtering enhancement. So the shortcomings such as image detail loss with single histogram equalization image enhancement method and enhancement image noise are overcome. Experimental results show that the method has better effect for image resolution and contrast enhancement.
