Abstract

Histogram equalization is one of the image enhancement techniques which has gained widespread popularity nowadays. It is a spatial domain histogram manipulation technique which mainly deals with brightness value remapping for recovering the lost contrast. In this paper an experimental study of the performance of histogram equalization technique on images has been done using matlab. Image multiplication and image division techniques are done on images in such a way that by adjusting the respective constant values, the contrast of the image is been made poor. To recover the lost contrast and the image back, the technique of histogram equalization is used and a comparison of the resultant image with original image and an analysis of the performance of this technique is done. The appearance of the images get enhanced by histogram equalization. The method uses the principle of stretching out the grey levels of the less contrast, darker image thereby producing a uniformly distributed flat histogram and a more contrast clear image.
