Abstract |
Histogram equalization is a very popular technique for image contrast enhancement. However, it at times produces a washed-out appearance of the small details present in an image. In this paper, a modified contrast enhancement technique based on conventional histogram equalization algorithm is proposed. This technique modifies the accumulations in the histogram bins of an image before applying the equalization process so that it performs the enhancement of the image without making any loss of details in it. This method outperforms other present approaches by enhancing the contrast well without introducing washed out appearance, checkerboard effects or any such undesirable artifacts. |
