Histogram-shape preserving algorithm for image enhancement
Tian-Hu Yu, Sanjit K. Mitra · 1993 IEEE International Symposium on Circuits and Systems · 2002
A new direct contrast enhancement algorithm is proposed. It can be used to enhance the contrast of an image without increasing the dynamic range of the pixel values. A distinctive property of the proposed method is that it yields results matching the characteristic of the human visual system. The histogram of the enhanced image has almost the same shape as that of the original image.>
