Problems solved by technology
In the prior art, image edges are mainly smoothed directly through various existing smoothing algorithms. However, after directly calling the existing smoothing algorithms to smooth the image edges, although a smooth curve can be obtained, the degree of distortion of the curve More serious, the image contour represented by the curve is often quite different from the original image contour, making it difficult to use the curve in the subsequent processing of the image
It can be seen that the existing image edge smoothing methods have the problem of serious distortion after edge smoothing

An embodiment of the present specification provides an image edge smoothing method and device, which can smooth the image edge into a curve, reduce the degree of distortion of the image edge while smoothing, and improve the accuracy of edge smoothing. Wherein the method comprises: acquiring the image to be smoothed, aiming at the jagged image edge to be smoothed in the image to be smoothed, determining the trend inflection point of the image edge in the image edge, and adjusting the image edge according to the trend inflection point Segmentation; chamfering the corners in each segment of the lines obtained by the segmentation, and deleting redundant vertices in the edge of the image after chamfering through a preset redundant vertex deletion algorithm; after the vertices are deleted In the edge of the image, judge whether each newly generated corner meets the preset smoothing distortion requirement, and obtain the judgment result; according to the judgment result, the edge of the image after the vertex is deleted is smoothed into a curve by a preset smoothing algorithm .
Description
technical field [0001] This document relates to the field of computer technology, in particular to an image edge smoothing method and device. Background technique [0002] At present, in the field of image processing technology, how to smooth the edge of an image into a curve is a relatively popular research direction. In the prior art, image edges are mainly smoothed directly through various existing smoothing algorithms. However, after directly calling the existing smoothing algorithms to smooth the image edges, although a smooth curve can be obtained, the degree of distortion of the curve More seriously, the image contour represented by the curve is often quite different from the original image contour, making it difficult to use the curve in the subsequent processing of the image. It can be seen that the existing image edge smoothing methods have the problem of serious distortion after edge smoothing. Contents of the invention [0003] The purpose of an embodiment of...
