Image Enhancement takes important part in medical image processing. In this paper, a new image enhancement method for medical images based on 2D empirical mode decomposition (EMD) is proposed. Firstly, we decompose the image into low-frequency information and high-frequency information by 2D EMD. Then expand the high-frequency part. Finally add the expanded high-frequency information with the low-frequency information and enhanced image is obtained. Experiments show that good results are obtained by using the proposed method.
