Abstract

In order to improve the shortcomings of X-ray imaging such as low contrast, apparent noise of background and the details of the workpiece can not be shown, Alterable framework model on Retinex algorithm appeared. It strengthens characteristics of X-ray imaging and improved the contrast and the quality of the original images, and the best visual effects of the minutia area are achieved. The theoretical analysis and the result of the experiment indicate that this algorithm compared with other algorithms, such as Homomorphism Filter and Gray Equalize which can effectively enhance contrast, control the context and noise. After enhanced the radiographic images by using this algorithm, the images will have better contrast than the first and second algorithms.
