Abstract :
In this paper, we present a novel method for the display of high dynamic range images. The new method first computes a gain map image using a computational approach inspired by a machine learning algorithm and sums the gain map and the original image together; it then linearly scales the sum image to fit the dynamic range of the display devices. Results are presented to demonstrate the effectiveness of this new method and it is also shown that the new approach is an effective method for enhancing standard (8 bits/pixl) images.
