Contrast enhancement is the focus of this paper namely use of digital for medical imaging. Five types of images were analysed, namely hand, brain, head, ankle and knee. Three techniques have been used such as INT Operator, Fuzzy Type-1 and Fuzzy Type-2 on five different images. The obtained results have been compared based on four quality parameters, namely mean square error (MSE), normalisation coefficient (NC), root mean square error (RMSE) and peak signal to noise ratio (PSNR).Results showed INT Operator provides the best resultant image compared with other techniques.
