Problems solved by technology

Since zero-crossing points are sensitive to noise, many edge images obtained from zero-crossing points are false edges, and the pulling effect of false edges may make the optimal path not a real edge

Abstract

The embodiment of the invention provides a tubular object segmentation method, device and equipment. The method comprises the steps that path coordinate information of a tubular object to be segmented is acquired, and local grayscale range and a target candidate area corresponding to the tubular object are determined according to the path coordinate information; edge detection is performed on the tubular object in the target candidate area so that edge information and gradient information are acquired; the key edge points of the tubular object are determined according to the edge information, the gradient information and the local grayscale range; and an optimal path between the key edge points is searched according to the key edge points so as to determine the border of the tubular object. Segmentation accuracy of the tubular object can be effectively enhanced by the tubular object segmentation method, device and equipment.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a tubular object segmentation method, device and equipment. Background technique [0002] In the technical field of image processing, it often involves the segmentation of tubular objects in two-dimensional images. For example, in angiography (English full name is Digital Subtraction Angiography, English abbreviation is DSA) images to extract the cardiovascular with diseased parts, and analyze the stenosis of the extracted cardiovascular, which is helpful for doctors to diagnose cardiovascular diseases. [0003] In the prior art, as in the DSA image, there are usually two ways to segment the tube. One is fully automatic segmentation and the other is interactive segmentation. Fully automatic segmentation generally operates on full-frame images, and generally uses the maximum entropy threshold method, template matching tracking method, etc. Interactive segmentat...
