Method and system for detecting and removing raindrops in light rain scene video data

Abstract

The invention provides a method and system for detecting and removing raindrops in light rain scene video data. The method for detecting the raindrops includes the steps that pixels to be processed in initial color video images are extracted; whether the corresponding brightness difference, in the two adjacent frames of images, of the pixels falls in a preset range or not is judged, and the pixels falling in the preset range are brought into initial check results; the variable quantity of a single channel representing a color attribute and / or the difference between variable quantities of two channels representing color attributes, in the two adjacent frames of images, corresponding to the pixels is compared with a set threshold value to screen the initial check results, and a screening result marked with the raindrop pixels is obtained. According to the method and system for detecting and removing the raindrops, the brightness difference between the two frames in a light rain scene can be used for a raindrop initial check, chromatic characteristics are used for constraint to eliminate non-rain components, the real raindrops are detected out, and finally the raindrops are removed to recover a video; the correct rate of raindrop detection is increased, the omission ratio is reduced, and the quality of video recovery is improved.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method and system for detecting and removing raindrops in light rain scene video data. Background technique [0002] Due to the development of computer vision technology, people have higher and higher requirements for information processing, and now with the construction of the information highway, the widespread use of the Internet and the intelligentization of the way people obtain information, image information is very important . Human beings obtain information mainly through images and voice, among which visual information accounts for more than 70%. Therefore, the development of image transmission and processing technology plays an increasingly important role in intelligent transportation, scientific research, military defense, security monitoring and other fields. more important role. Due to the increasing popularity of computer vision systems outdoors, rainy fields in ba...
