Abstract

The present invention provides an automatic positioning method for finger-wrist joints based on image template matching. The user selects a hand-shaped frame, and the hand fits the hand-shaped frame to take a picture, and the automatic finger-wrist joint positioning method based on image template matching performs finger / wrist joint positioning on the photo. The finger positioning result returns the coordinates of 15 finger joint points and the corresponding finger width, and the wrist positioning result returns the coordinates of two wrist points and the wrist width. The user can process and use the returned results to realize finger / wrist jewelry try-on. The present invention does not require that the fingers and wrists completely fit into the hand-shaped frame when taking pictures, and the joint points can be accurately positioned even in the case of a certain deviation. The present invention has no specific requirements on skin color, and the method of sampling skin color can adapt to different skin colors. Meanwhile, the automatic positioning method of finger and wrist joints based on image template matching is applicable to various complex backgrounds and can provide accurate positioning.

Description

technical field [0001] The invention generally relates to the field of computer digital image processing, in particular to an automatic positioning method for finger, wrist joints based on image template matching. Background technique [0002] In recent years, with the rapid progress of society and the continuous enhancement of national strength, digital image processing has been widely used in all aspects of life. The concept of try-on has been mentioned repeatedly, but the real application is still not widespread enough. There are very few try-on software popular in the market, and jewelry try-on software is even rarer. With the rapid development of e-commerce, online shopping has become a new shopping mode, and its development is becoming more and more popular. How to let users choose the most suitable style for online jewelry shopping depends on a few pre-beautified Jewelry pictures that have been passed cannot meet the needs. At this time, the try-on software came into...
