Identity identification method based on ultrasound whole heart sequential images

Abstract

The invention relates to an identity identification method based on ultrasound whole heart sequential images. The method comprises the steps of (1) collecting the ultrasound whole heart sequential images of the objects needed to be identified; (2) conducting segmentation on the four cavities of each image collected in the step (1), and then calculating geometric properties of the four cavities of each image; (3) arraying the geometric properties of the four cavities obtained in the step (2) according to different geometric properties and the sequential images, and obtaining a characteristic curve of the movement of the four cavities with different geometric properties; (4) processing the characteristic curve of the movement of the four cavities, and extracting key points of the characteristic curve of the movement of the heart; (5) comparing the time differences of the key points with identical characters of the characteristic changing curve of the four cavities, and obtaining synchronization information of the four cavities; (6) calculating statistics of the geometric characteristics of the four cavities of the heart in cardiac cycle; (7) conducting identification; (8) outputting the result.

Description

technical field [0001] The invention belongs to the field of image recognition, and in particular relates to an identity recognition method based on ultrasonic whole heart sequence images. Background technique [0002] With the rapid development of information technology, the network has become an indispensable part of people's life. At the same time, the security of information is also facing great challenges. How to accurately realize identity recognition has become an important research topic. [0003] Traditional identification methods such as personal documents and ID cards need to be carried with you, and are easy to be lost or stolen. Once stolen or embezzled, your own security and privacy will be threatened. [0004] Under modern technology, people have expanded face recognition and fingerprint recognition technology, but the problem with these two technologies is that they can be replaced by photos or twin siblings, and fingerprints can be forged with silica gel, wh...
