The quality of the image is one of the important influential factors in the process of defect evaluation of weld radiographic image. To improve the brightness and contrast of digital image of weld radiographic film, a new quality enhancement method in accordance with human visual system is proposed. The human visual resolution ability of the gray and the imaging model of digital system are introduced, then the gray-level mapping transformation function is given in this paper. The processed… CONTINUE READING
