Abstract

The invention discloses an image defogging method and a terminal. The image defogging method comprises steps that a sky area of a to-be-processed image is separated according to an optimal approximately normal distribution fitting algorithm, and the sky points and the non-sky points of the to-be-processed image are determined; the local histogram equalization processing of the non-sky points is carried out, and the assignment processing of the sky points is carried out, and then the defogged image is acquired. According to the technical scheme provided by the invention, the sky points and the non-sky points of the to-be-processed image are discriminated, and the local histogram equalization processing of the non-sky points is carried out, and therefore the wrong enhancement of the sky area having slow gray scale change is prevented during the local histogram equalization processing, and the defogging effect of the image is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image defogging method and a terminal. Background technique [0002] Fog is a common natural phenomenon. In a foggy environment, turbid media such as small water droplets and dust in the atmosphere will scatter and absorb light, reducing the contrast of the captured image and changing the scene information in the image. It's blurry. Due to the serious impact of the turbid medium in the atmosphere on the acquisition of outdoor images, the outdoor image acquisition system cannot work normally, which brings some inconvenience to outdoor operations such as terrain exploration and video surveillance. Therefore, for various images in foggy days It is of great practical significance to perform defogging processing on the images acquired by the acquisition equipment. In recent years, with the continuous development of computer software and hardware technology, it ha...
