Paper Abstract

Due to the special features of the homomorphic filter, relying on its capabilities of selectively enhancing blurred images with poor contrast and nonuniform illumination, a study concerning the possibility of applying it to RGB (24-bit true color) images has been made. Moreover, the effects of different shapes for the linear filter employed by the process are discussed and illustrated using a classical high pass butterworth filter modified for more flexibility in the final enhancement. An image of poor quality in terms of blurring and nonuniform illumination was used to demonstrate the results of different stages of the filtering process. It is shown that homomorphic filtering is a viable tool for enhancing poor quality RGB images.
