Method and device for extracting hand region of interest

Abstract

A method and a device of extracting a region of interest of a hand are provided. The method comprises the following steps: extracting a hand contour from a hand image; extracting feature points used for representing the features of the hand contour from the extracted hand contour, wherein the feature points include general feature points and auxiliary feature points; and extracting a region of interest of the hand according to the general feature points or according to the general feature points and the auxiliary feature points. By extracting the feature points for representing the features of the hand contour from the hand contour instead of directly selecting a region of interest of a hand by a doctor based on experience, a region of interest of a hand can be extracted more quickly and accurately, and the treatment of rheumatic joint diseases of the hand is facilitated.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for extracting a hand region of interest. Background technique [0002] For a long time, joint diseases such as rheumatoid arthritis have seriously endangered people's health. Severe joint diseases will lead to decreased or even loss of joint function. Among them, the hand joints are one of the main parts where diseases such as rheumatoid arthritis occur. Therefore, how to quickly and accurately diagnose hand joint diseases has become a problem that people pay more and more attention to. [0003] In practical applications, an image of a certain part of the human body, for example, an image of a hand, can be obtained through existing imaging technologies. However, no matter whether the acquired image is a two-dimensional image or a three-dimensional image, often only certain regions play a decisive role, and these decisive regions can be called regions of inte...

Problems solved by technology

However, since different parts of the human body have different structural characteristics, the above extraction techniques are not suitable for hand ROI extraction

[0005] In the existing clinical diagnosis of hand and joint diseases, the extraction of the region of interest is still mainly selected by the doctor manually. On the one hand, this process will consume a lot of time; on the other hand, the accuracy of the region of interest selection is largely Relying on the doctor's experience, resulting in unstable selection results
