Embodiment Construction

[0047] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] refer to figure 1 , shows a flowchart of steps of an image edge detection method according to an embodiment of the present invention.

[0049] The image edge detection method of the embodiment of the present invention may include the following steps:

[0050] Step 101, for the current pixel in the image to be processed, according to the pixel value of the current pixel, determine the adjustment parameter corresponding to the current pixel; the adjustment parameter is used to adjust the strength of the cut-off effect of Gaussian difference filtering.

[0051] Step 102, for each neighboring pixel of the current pixel, according to the coordinate difference between the current neighboring pixel and the current pixel, determin...

Abstract

The invention provides an image edge detection method and device, electronic equipment and a storage medium. The image edge detection method comprises the following steps: for a current pixel in a to-be-processed image, determining an adjustment parameter corresponding to the current pixel according to a pixel value of the current pixel; for each neighborhood pixel of the current pixel, determining a first spatial domain weight and a second spatial domain weight of the current neighborhood pixel according to a coordinate difference value between the current neighborhood pixel and the current pixel; determining a Gaussian difference filtering parameter corresponding to the current pixel according to the adjustment parameter, the pixel value of each neighborhood pixel of the current pixel, the first spatial domain weights and the second spatial domain weights; and determining an edge characteristic value of the current pixel according to the Gaussian difference filtering parameter corresponding to the current pixel. Edge detection is more accurate, and the detection effect is better.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image edge detection method, device, electronic equipment and storage medium. Background technique [0002] Edge detection is a basic problem in image processing and computer vision. The purpose of edge detection is to identify points with obvious brightness changes in digital images. Significant changes in image attributes usually reflect important events and changes in attributes. Edge detection is a research field in image processing and computer vision, especially in feature extraction. [0003] Commonly used edge detection algorithms include Sobel, Prewitt, Roberts, Canny, and so on. However, the detection effect of current edge detection methods is poor. Contents of the invention [0004] In view of the above problems, embodiments of the present invention are proposed to provide an image edge detection method, device, electronic device, and storage ...
