Abstract:
Objective To select the proper enhanced methods of histogram egualization for the medical digital image. Methods By means of the full-frame histogram equalization(FFHE),local-area histogram equalization(LAHE) and adaptive-meighborhood histogram equalization(ANHE),medical digital images were enhanced,and the characteristics of these three methods were compared. Results Through the gray-level histogram equalization,the detail and the edge of medical digital images could be enhanced. Conclusion Toenhance the detail of local issue,it is better to use ANHE method.To enhance the edge of full image,which the full information must been taken into account,it is better to use FFHE method.
