Abstract

The invention discloses an image processing method and device, a storage medium and electronic equipment. The method comprises the following steps: acquiring a difference region in a first image and a second image; wherein the first image and the second image are images to be compared; respectively determining a minimum enclosing rectangle of the contour corresponding to each difference area to obtain a minimum enclosing rectangle set; combining a plurality of external rectangles of which the adjacent or overlapping degree is greater than or equal to a preset threshold value in the minimum external rectangle set to obtain a target external rectangle set; the adjacent or overlapping degree is the ratio of the first area to the second area; wherein the first area is the sum of the areas of any two circumscribed rectangles in the minimum circumscribed rectangle set, and the second area is the area of the minimum circumscribed rectangle of the union set of any two circumscribed rectangles. The technical problem that the image change information extraction efficiency is low is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular, to an image processing method and apparatus, a storage medium, and an electronic device. Background technique [0002] The automatic detection of image change area is an important means to effectively extract image change information, and is the basis for using image change information. At present, many researches focus on the detection of image change areas, such as image change detection based on Scale-Invariant Feature Transform (SIFT) feature points, or use of pattern recognition and other means for comparative analysis, etc. However, in the related art, for image change detection, only the image information contained in the identified multiple change areas is extracted separately, but the adjacent change areas of the image cannot be effectively integrated. Therefore, for the information of the image change area The extraction efficiency is low. SUMMARY OF T...
