Embodiment Construction

[0067] The invention relates to image information processing technology, mainly to repair the video image polluted by raindrops, which is beneficial to the further processing of the image, and improves the performance of image-based target detection, identification, tracking, segmentation and monitoring technologies.

[0068] This embodiment provides a method for removing the rain field in video data, which is actually a modified method for selectively detecting and removing raindrops according to the actual situation of the video image, effectively avoiding the inability to effectively target the video in the prior art. The problem of effective raindrop detection and removal in real-world images. Such as figure 2 As shown, the method of rain field removal in the video data of the present embodiment is as follows:

[0069] Step 110, extracting video image data representing brightness information in the initial video data;

[0070] Step 120, extracting pixels to be processed...

Abstract

The invention relates to the field of image processing and provides a method and system for removing rain fields in video data. The method includes: extracting video image data representing brightness information in initial video data; extracting pixels to be processed in the video image data ; Determine whether the skewness of the corresponding brightness value of the pixel in the multi-frame image falls within the preset range. If not, count the number of pixels with the skewness greater than the upper limit of the preset range. When the number of pixels exceeds When the first predetermined value is reached, the raindrops in the video image data are removed based on the motion segmentation method; if so, a parameter value representing the size of the rain is calculated, and different methods are selected according to the size of the parameter value. Raindrops are removed from video image data. The present invention can process color video data and select a suitable raindrop removal method by judging the video before rain removal processing.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and system for removing rain field in 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 bad weather have a great impac...
