| Abstract: | According to the gray-scale properties of chest radiograph, the local segmentation and the adjusting effects of linear transformation of three sections were analyzed, and an approach of blind enhancement without modifying parameters of gray-scale transformation was given in the paper. It is shown that the details of whole chest image are sharper and the method can be employed in most of clinic situation due to its convenience and rapid processing through the application of normal and SARS images. |
