Abstract :
When inspecting radiographics, some detail information cannot be detected due to large range of gray scales and complex tissue structure. The proposed approach of Gauss-Laplacian pyramid structure can amplify the detail information and resist noise by non-linear processing at different scales. The enhanced detail information is then added back to the original image iteratively, and the improved image is consistent to the characteristics of human being´s vision system, thus provides doctors with reliable evidences for diagnosis.
