Problems solved by technology

When the target in the image to be recognized is small and there is too much background information, the image recognition model usually cannot correctly identify the image
Although image recognition combined with existing ROI search methods or image recognition using object detection can solve this problem, such methods have a high amount of calculation and algorithm complexity, which brings a lot of time consumption

Abstract

The invention relates to an image recognition method based on edge extraction, which belongs to the technical field of image recognition. The method includes: performing grayscale processing on an image to be recognized to obtain a first grayscale image; and performing noise reduction and smoothing on the first grayscale image. process to obtain a second grayscale image; perform edge detection on the second grayscale image to obtain an edge information map; perform binarization processing on the edge information map to obtain a binarized image; determine the target area by traversing the binarized image. The bounding box is obtained to obtain a binarized image with a bounding box; the image to be recognized is cropped according to the bounding box in the binarized image with a bounding box to obtain a cropped image; the cropped image is used for image recognition. The invention cuts the image to be recognized according to the bounding box, thereby realizing low-cost and high-efficiency extraction of the region of interest, solving the adverse effect of excessive background information on the performance of the image recognition algorithm, and helping to improve the accuracy of image recognition.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to an image recognition method and system based on edge extraction. Background technique [0002] At present, in the existing image recognition methods, the image to be recognized is often directly scaled, and then the scaled image is input into the image recognition model for recognition. When the target in the image to be recognized is small and the background information is too much, the image recognition model usually cannot correctly recognize the image. Although combining the existing ROI search methods for image recognition or using object detection for image recognition can solve this problem, such methods have high computational complexity and algorithm complexity, which brings a lot of time consumption . SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an image recognition method based on edge extraction, which reduces the ...
