Method for contrast enhancement in colour digital image |
摘要 |
A method for improving the quality of a digital image acquired with a non-optimal exposure. The method, which is applied directly to the image in CFA (Colour Filter Array) format, identifies the regions of the image that are most important from the perceptive or contentual point of view by means of simple statistical measures. The image is then transformed by inverting the response function in such a manner as to optimize the quality of these regions. <IMAGE>
