Method and device for determining image boundary function

Abstract

The present invention is applicable to the technical field of image recognition, and provides a method and device for determining an image boundary function. The method includes: extracting a plurality of boundary coordinate points of a boundary area in an image to be recognized; Divide a plurality of boundary coordinate points to obtain a plurality of boundary coordinate groups; determine the boundary function of the image to be recognized according to any one of the boundary coordinate groups through a preset boundary function determination algorithm; determine the boundary function Whether it conforms to the preset image boundary function judgment rule; if so, determine the boundary function as the image boundary function corresponding to the image to be recognized, thereby solving the existing determination technology of the image boundary function, and fitting the image boundary function through all boundary coordinates , the coordinate points with large errors are also used as reference points for fitting the image boundary function, resulting in the problem that the obtained image boundary function cannot truly reflect the image boundary, and the accuracy rate is low.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to a method for determining an image boundary function and a device thereof. Background technique [0002] With the development of image recognition technology, users have higher and higher requirements for the accuracy of image recognition results. The determination of image boundary function, as the basic link of image recognition, directly affects the accuracy of recognition results. However, the existing image boundary function determination technology uses all the boundary coordinates to fit the image boundary function. If some boundary coordinates are affected by noise and deviate from the original boundary, a large error will be introduced into the fitting image boundary function, resulting in The obtained image boundary function cannot truly reflect the boundary of the image, and the accuracy rate is low.
