Abstract

Brightness transformation of low-level-light images, which only depends on the characteristics of every pixel, can change the brightness of pixels. In this paper we firstly analyze the low-level-light images, proposing two ways to transform the brightness of pixels: brightness correction and gray-scale transformation. And during the brightness correction is changing the brightness of pixels, it is necessary to consider something such as the brightness it used to have and its position in the image. While gray-scale transformation doesn't need to consider its position in the image during it's modifying the brightness of pixels.
