Aim:Image enhancement is used to improve the quality of images and it enhances,sharpens image features such as edges,boundaries and contrast to make a graphic display useful for display and analysis. In order to enhance the quality of images innovative image enhancement technique using histogram method ism developed in this work. Materials and Methods: In this research, a contrast limited adaptive histogram based image enhancement technique is proposed and developed for images and the proposed work is compared with another image enhancement technique called median filtering method.Input medical images (N=30) of both groups were downloaded from standard medical databases. The average power is set to 80%, Threshold 0.05 and 95% of confidence intervals for sample size calculation.
