Embodiment Construction
[0042] Based on the image rain removal technology in the field of machine vision, the present invention provides a method for quickly removing image rain lines based on a single image. By using a specific threshold and image extraction window size, the image local entropy information is calculated to determine the image containing rain. Afterwards, the corresponding image edge recognition method is used to synthesize the calculation results of the previous step to obtain an improved rain line part map; and then the rain line is removed through image arithmetic operations. This method effectively improves the image rain removal effect, and does not use complicated Logic operation simplifies the calculation process of computer programs, shortens the image processing time, can effectively process color images with large amounts of data, and based on its short calculation time, it can be effectively applied to the real-time processing of video data to improve real-time Monitor the c...

The invention provides a single-image based image rain streak eliminating method and system. The method comprises extracting the pixel gray level of an image to be processed on the basis of a set local image window; computing the corresponding image local entropy of every image block inside the local image window; extracting the image blocks with the image local entropy larger than or equal to a preset value to form a first intermediate image; identifying the edge of image elements inside the image to be processed, and processing the image region inside the edge through image morphological operations to obtain a second intermediate image; extracting the intersection of the first intermediate image and the second intermediate image to obtain a contour image of the image to be processed with rain streak parts eliminated; intersecting an image, which is obtained through data standardization of the contour image, with the image to be processed to obtain a result image with rain streaks removed. The single-image based image rain streak eliminating method can rapidly eliminate influence of raindrops in the image and increase the image processing speed.
Description
Technical field [0001] The present invention relates to digital image processing technology, in particular to a method and system for removing image rain lines based on a single image. Background technique [0002] Due to its many advantages including automation, intelligence, and high efficiency, outdoor computer vision systems are widely used in military and national defense, medical technology, intelligent transportation and other fields. However, bad weather will seriously affect its performance and even lead to its complete failure. Therefore, an effective method to eliminate the influence of bad weather is essential for an all-weather outdoor vision system. In many severe weather conditions, due to the large particle (raindrop) radius and other complex physical characteristics of rain, the quality of images captured by the visual system will be greatly affected. Image raindrop removal technology uses the physical and frequency characteristics of rain to identify and remov...
