Notebook paper and classification icon identification method

Abstract

A method for identifying notebook paper and classification icons, which includes the following steps: the notebook uses detachable paper, and each page is provided with a black edge at least 3 mm wide; the main color of the background of each page is white, and the white background is provided with paper lines and Classification icon; 2. Paper recognition: first input the image, perform image preprocessing, and then extract the circumscribed rectangle of the paper outline in the image, and finally output the coordinates of the four corners of the paper circumscribed rectangle in the shooting device; 3. Classify icon recognition: press Proportionally intercept the area where the classification icon is located, and traverse the area in equal proportions according to the width of the classification icon. The area with the most pixels with a pixel value of 0 is the classification area marked by the user, so as to determine the classification; more intelligent and fast classification, extremely Greatly improved user efficiency.

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...

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.
