YU Dai,BAO Xudong(Laboratory of Image Science and Technology,Southeast University,Nanjing 210096)  
In order to enhance the image contrast as well as to represent the image details,we propose a new multi-scale contrast enhancement algorithm which separates the low frequency signals and the high frequency signals of the image in logarithmic domain,processes them separately by using HE method and local contrast enhancement.This method integrates HE and local contrast enhancement and finally produces a visually comfortable result image.
