Hybrid Contrast EnhancementFor X-ray Images

Abstract

The applications of x-ray are highly increased for different medical and industrial proposes . But the x-ray images always very dark and with low contrast. The digital image enhancement techniques have become a major process for extracting information from the sample structure and make the interpretation of these images easier. So, in this study we used two enhancement techniques to improve x-ray image appearance and contrast. The 1st, method is the sliding histogram operations, and the 2nd, method is the histogram equalization, these used to improve dynamic image range and improved contrast image quality. The results show that the x-ray image quality enhanced and image contrast highly increased by using these methods, especially histogram equalization.
