Abstract

The invention provides an image processing method applied to an image processing system. The image processing method comprises: (a) computing an image intensity distribution of an input image; (b) performing atmospheric light estimation to the input image; (c) performing transmission estimation according to a result of the step (a) to the input image, to generate a transmission estimation parameter; and (d) recovering scene radiance of the input image according to a result generated by the step (b) and the transmission estimation parameter. At least one of the steps (a)-(c) are performed to data corresponding to only partial pixels of the input image. The invention further provides a corresponding system. The fuzzy can be eliminated with less data calculated amount.

Description

technical field [0001] The disclosed embodiments of the present invention relate to image processing, and more particularly, to an image processing method and image processing system. Background technique [0002] Turbid media such as particles or tiny water droplets in the atmosphere often degrade the image quality, especially in outdoor scenarios. Phenomena such as haze, fog and smog are caused by atmospheric absorption and scattering. In this scenario, the image may lose color contrast or color fidelity, so that the image may lose image detail and have poor image quality. [0003] Therefore, image de-hazing methods are developed to solve these problems. However, traditional image deblurring methods usually require a high amount of data calculation, so the processing time of image deblurring is always relatively long. Contents of the invention [0004] Therefore, an object of the present invention is to provide an image processing method and an image processing system...
