Abstract

An image segmentation marking method taking area features of pixel as base comprises the following steps: when acquiring an input image, performing progressive scan of the pixel of the image by line, determining the mark not marking pixel in the input image according to the area features of adjacent pixels of each pixel, recording pixel update information to generate an area mark update data table and an area mark feature data table, and then performing the progressive scan of the pixel of the input image again to obtain the mark of the pixel, and finally judging and updating the area mark ofthe pixel according to the area mark update data table.

Description

technical field [0001] The invention relates to an image segmentation method, and in particular to an image segmentation and marking method based on the regional characteristics of pixels. Background technique [0002] "Image Segmentation" is to segment the object of interest from the input image, which is used in image recognition, image compression, image retrieval and monitoring systems. Traditionally commonly used image segmentation methods include histogram-based image segmentation methods, edge detection-based image segmentation methods, and region-based image segmentation methods. [0003] The histogram-based image segmentation method analyzes the statistical histogram (Histogram) of the entire or part of the image to determine an appropriate threshold as the basis for image segmentation. The image segmentation method based on edge detection analyzes the change of image brightness between the object and the background, and finds the edge of the object as the basis fo...
