Abstract

The invention discloses a color image edge extraction method, and belongs to the technical field of image processing. The invention discloses a color image edge extraction method, and the method comprises the following steps: S1, noise reduction: performing noise reduction on an image by adopting a noise reduction method based on a threshold value; S2, image color structure analysis: carrying out color analysis on the image structure through an RGB model and an HSI model; S3, designing of an algorithm to extract a color edge: designing an algorithm comparison threshold, determining color edge points, and forming the color edge by a plurality of edge points. According to the method, the accuracy of color image edge extraction is improved, and a good basis is provided for subsequent image processing.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for edge extraction of a color image. Background technique [0002] With the rapid development of computer network technology, the ability of human beings to obtain data has been continuously enhanced, and the application of images has become more and more extensive, playing a significant role in people's daily life. In digital image processing, edge information is an important feature information of an image, and it is an important part of image processing and computer vision. Among them, image edge feature extraction is the basis of the above application; the result of image edge extraction will directly affect the next operation. [0003] The edge position of the image is generally where the color of the image changes drastically; these changes are often caused by the shape and structure of the object, which reflects light under the external ambient light; t...
