Abstract

The invention is suitable for the technical field of image processing, and provides an image segmentation method and terminal equipment, and the method comprises the steps: carrying out the high-frequency enhancement of the light of a to-be-segmented image, and obtaining a first image; performing bilateral filtering processing on the first image to obtain a second image; performing gradient calculation on each pixel point of the second image and applying non-maximum suppression to obtain a third image; calculating gray value thresholds of a target area and a background area of the third imageaccording to the gray value of the third image; and segmenting the third image according to the gray value threshold. According to the method, image high-frequency enhancement processing and bilateralfiltering processing are carried out; according to the method, the clearer image is obtained, the influence of weak illumination on the segmentation effect is solved, then the proper gray value threshold value is automatically selected, and the target area is identified, so that the interference of noise is effectively reduced, the target area of the image is rapidly segmented, and an edge breakage phenomenon does not exist.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an image segmentation method and terminal equipment. Background technique [0002] Usually, before image recognition, it needs to be segmented, and then recognition and other processing are sequentially performed on the segmented image. The key to image segmentation is to identify the image edge. Because the image edge determines the image contour, it becomes the key part of the background area and target area segmentation, so the image edge detection technology has become the focus of research. At present, differential operators are the most popular classical edge detection operators. For example, differential operators include Soble operator, Laplace operator, and Canny operator, etc., but each differential operator has its applicable range, and in the processing process There are limitations in . Among them, the Canny operator is a relatively mature algo...
