Abstract

The disclosure relates to an ear key point detection method, device and storage medium, and belongs to the field of image processing. The method includes: acquiring a human face image, the human face image includes key points of human face contour, and the key points of human face contour are used to determine the ear region in the human face image; acquiring the ear key point detection model, the The ear key point detection model is used to detect ear key points in any ear region; based on the ear key point detection model and the position of the human face contour key point in the human face image, the detection Ear key points in the face image. The ear area is determined by using the key points of the face contour, and the ear key points in the face image are detected by using the ear key point detection model, taking into account the positional relationship between the ear area and the face contour, and through the ear The key point detection model learns the way to detect ear key points in the ear area, which improves the accuracy of ear key points and reduces the error.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to an ear key point detection method, device and storage medium. Background technique [0002] In recent years, with the rapid development and wide application of image processing technology, in various fields such as virtual reality and short video, it is usually necessary to detect the key points of the ear in the face image, and then make a comparison based on the detected key points of the ear. The ear area in the image is operated, such as the operation of adding decorations, etc. [0003] Move a circular area of ​​a certain size in the face image including the ear area, scan the face image located in the circular area, and highlight the gray level according to the different gray levels of the pixels in different parts of the ear area The pixel points of the outer auricle are determined as the edge points of the outer auricle, thereby determining a plurality of edg...
