In this paper, the disadvantage of using traditional histogram equalization for infrared image enhancement is discussed. Then by analyzing the human visual responds to the logarithm of image lightness, a modified method of histogram equalization algorithm is proposed based on the visual characteristic. The method can improve the displaying ability of image details through adjusting the pixel contrast...
This paper introduces two concepts of the traditional quality evaluation: the subjective evolution and objective evaluation, and then several kinds of common used human visual perception image quality judgment criterion are introduced, such as: assessing the quality of enhanced images based on human visual perception, image quality assessing model by using neural network and support vector machine,...
Maintaining image quality under various lighting conditions is critical to portable multimedia devices. In this paper, an image enhancement algorithm is proposed to deal with extremely dim LCD backlight (or strong ambient light) under which the image often becomes imperceptible. The crux of our idea is to keep the detail content of the image in the visible luminance range. To do that, a two-layer...
