Enhancement of Bone Fracture Images by Equalization Methods

Abstract

A fracture is a crack or break in the bone. This can be easily detected by taking an X-ray in that area. But some times these images lack sufficient brightness. Various Equalization Methods can be adapted to enhance the image. In this paper, two such methods are compared. They are Histogram Equalization and Contrast Limited Adaptive Histogram Equalization. The results show that Contrast Limited Adaptive Histogram Equalization gives better result than other Equalization method.
