Abstract

Pre-processing is the basic step to reconstruct the image with some useful feature. This technique is essential for the enhancement of knee images which increases the efficiency of the subsequent tasks of the knee recognition system. In this paper, an hybrid approach is proposed which is a combination of contrast stretching and adaptive thresholding that simultaneously adjusts the intensity level of knee images using boundaries is developed. The validation of proposed system is carried out based on the defined parameter matrices. The experimental results shows that the proposed method proves efficient when compared to other traditional methods.
