Problems solved by technology
These contour detection methods have some defects, including the relatively simple applicable scene, and cannot obtain effective edge information for unclosed image contours. When the background is complex, using existing methods can only obtain all the contours in the background, but cannot be accurately extracted. to the real contour of the image to be processed

The embodiment of the present application discloses an image extraction method and related products, wherein the image extraction method is applied to the area image extraction corresponding to the object parallel to the opposite side, including: acquiring the image to be processed, and dividing the image to be processed into blocks to obtain multiple areas block image; determine the scanning area size of each area block image in a plurality of area block images; scan each area block image according to the scanning area size of each area block image, and obtain the contour extraction result corresponding to the image to be processed; according to The contour extraction results determine the target area image in the image to be processed. In the embodiment of the present application, multiple region block images are obtained by dividing the image to be processed into blocks, and each region block image is scanned to obtain a contour extraction result, and then the extracted target region image is determined according to the contour extraction result. This can reduce threshold calculations, improve the accuracy of effective contour information extraction, and ultimately improve the efficiency of extracting target area images.
Description
technical field [0001] This application relates to the technical field of image processing, in particular to an image extraction method and related products. Background technique [0002] In the process of image processing, it is necessary to extract the effective information of the image, so it is necessary to extract the outline of the effective image. This technology has been widely used in license plate recognition, face recognition and dynamic tracking, etc. The application of this technology reduces a lot of time consumption and brings great convenience. [0003] At the same time, in image recognition, the real outline of the effective area is obtained, which reduces the amount of calculation and improves the accuracy of detection. Most of the existing contour detection methods are aimed at simple backgrounds, mainly using operators based on sobel, roberts, prewitt, laplacian and canny. These contour detection methods have some defects, including the relatively simpl...
