Notebook paper and sorting icon recognition method

Abstract

A notebook paper and sorting icon recognition method comprises the following steps: 1, a notebook adopts detachable paper, and each page is provided with a black edge of at least 3mm width; the main color tone of each paper background is white, and the paper lines and classification icons are arranged on the white background; 2, paper recognition: firstly, an image is input, image preprocessing iscarried out, an outer rectangle of pap contour in that image is extracted, and finally coordinates of four corners of the outer rectangle in the photographing device are output; 3, identification ofthe classification icon: the region where the classification icon is located is intercept according to a proportion, and the region with the most pixels with the pixel value of 0 in the region is traversed according to the width of the classification icon in the same proportion, so as to determine the classification region demarcated by the user. Smarter and faster classification greatly improvesthe work efficiency of users.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a notebook paper and classification icon recognition method. Background technique [0002] At present, in order to ensure that their handwritten notes will not be lost or damaged over time, people use their mobile phones to take pictures of the current paper pages and upload them to computers or the Internet, and then manually classify their handwritten notes one by one. This will face three problems: [0003] 1. During the shooting, it is easy to capture a large area of ​​background other than the notebook paper, which to a certain extent causes obstacles to reading the content of the paper in the photo, and it is not beautiful; [0004] 2. When the photos taken are not ideal, in order to keep only the paper area in the photos, it is necessary to cut and process the photos, which takes a lot of time and energy; [0005] 3. After the paper photos are processed, people...

AI Technical Summary

Problems solved by technology

[0003] 1. During the shooting, it is easy to capture a large area of ​​background other than the notebook paper, which to a certain extent causes obstacles to reading the content of the paper in the photo, and it is not beautiful;

[0004] 2. When the photos taken are not ideal, in order to keep only the paper area in the photos, it is necessary to cut and process the photos, which takes a lot of time and energy;

[0005] 3. After the paper photos are processed, people like to classify their own photos. At this time, they need to manually put them into different categories one by one. This process will cause people to waste time and energy.
