Medical Image Enhancement Method Based on Mode Decomposition
نویسندگان
چکیده
Aiming at existing medical image enhancement method is unable to prominent part and detailed information and will be interfered by noise easily when medical image contrast is increased, this paper proposed enhancement algorithms combining the histogram equalization with image details preservation and bidimensional empirical mode decomposition. First, through the histogram equalization with image details preservation to increase the overall image contrast; and then based on bidimensional empirical mode decomposition, the medical image has been decomposed into the image information with different frequency, with various levels improvement of the information , to perform image enhancement. Through the comparison of proposed method with the traditional method, it has been verified the proposed method has a better effect in the detail enhancement of medical images.

Filtering vs. nonlinear estimation procedures for image enhancement
Image enhancement methods can be divided into two groups: the ones that use only one single image and the ones that rely on specific training set or use multiple images. In this paper an iterative algorithm, based on the quasi-Newton methods, is introduced with the objective to enhance resolution only by one single image. In the paper there will be compared results gained depending on the used ...
