Abstract

The invention relates to an image defogging method and system. The method comprises the following steps: inputting an original image, namely a colored fogged image; extracting a basic image and a detail layer of the colored fogged image, respectively; acquiring image data of three channels R, G and B of the basic image; solving the global airglow and transmissivity of each of the channels of the basic image, respectively; recovering a fogless image of each of the channels according to the global airglow and transmissivity of each of the channels of the basic image so as to acquire a fogless basic image; adding detail layer information into the fogless basic image; and carrying out smooth treatment as well as brightness and contrast enhancing treatment on the fogless basic image with the detail layer information to obtain a fogless original image. The method and system provided by the invention can be used for satisfying a real-time requirement and achieving a good defogging effect.

Description

technical field

[0001] The invention relates to an image defogging method and system. Background technique

[0002] In real life, we often encounter foggy weather, and the foggy pictures taken in foggy weather cannot be used normally due to low visibility, so there are many dehazing algorithms.

[0003] At present, there are many algorithms for defogging the fogged images in the prior art. Although this defogging method has advantages, it also has disadvantages. Some have good real-time performance, but the defogging effect is not good. The effect is good, but the real-time performance cannot meet the requirements. Contents of the invention

[0004] The technical problem to be solved by the present invention is to provide an image defogging method and system, which can not only meet the real-time requirement but also achieve a good defogging effect.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a m...
