Embodiment Construction

[0020] The technical solutions of the present application will be clearly and completely described below with reference to the embodiments of the present application and the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0021] The present application is a method for edge detection on an image. The edge detection identifies the points with obvious changes in the image. Therefore, the method of the present application realizes the identification of the edge points according to the neighborhood difference of the pixel points, which mainly includes two extraction steps. Firstly, the edge points are extracted based on the neighborhood difference degree, and then the neig...

Abstract

The present application discloses an image edge detection method, device and computer storage medium, wherein the method includes: acquiring the neighborhood difference degree of each pixel in the first detection area of ​​the image, and extracting the first neighborhood difference degree based on the neighborhood difference degree edge point; determine the second detection area according to the first edge point, wherein the second detection area is smaller than the first detection area; amplify the neighborhood difference of each pixel in the second detection area, and based on the enlarged The second edge point is extracted by neighborhood difference; the edge of the image is determined according to the first edge point and the second edge point. Through the method of the present application, weak edges in the image can be detected more accurately.

Description

【Technical field】 [0001] The present application relates to the field of image detection, and in particular, to an image edge detection method, an image processing device and a computer storage medium. 【Background technique】 [0002] Edge detection is a basic operation in image processing and can be applied to different fields. For example, in the industrial field, edge detection is used to detect the surface quality of workpieces. Specifically, the image of the workpiece surface is acquired, and then edge detection is performed on the image of the workpiece surface. To detect whether there are scratches on the surface of the workpiece. In specific applications, the scratches on the surface of the workpiece are often shallow, and the edge contrast in the image of the corresponding workpiece surface is weak, which is not easy to be detected. [Content of the invention] [0003] The present application provides an image edge detection method, an image processing device and a...
