Abstract

The invention relates to a target object key point detection model training method and a detection method and device. The method comprises the steps of obtaining a video sample, inputting a plurality of first to-be-detected image samples in the video sample into a candidate key point detection network, obtaining a first candidate key point corresponding to each first to-be-detected image sample, inputting the plurality of first to-be-detected image samples and the first candidate key points respectively corresponding to the first to-be-detected image samples obtained in the previous step into a self-encoding network to obtain a plurality of target generation image samples input by the self-encoding network; and updating the parameters of a candidate key point detection network based on the stability results of the plurality of target generated image samples until the stability results meet a first preset condition, and determining the candidate key point detection network as a target key point detection network, namely, training the candidate key point detection network based on the stability result of the plurality of target generation image samples as a convergence condition, thereby improving the stability of the target key point detection network.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a detection model training method, detection method and equipment for key points of a target object. Background technique [0002] With the development of image processing technology, beauty is widely used in application software such as short video shooting and webcasting. For example: in the process of webcasting, key points (such as: nose, eyes, etc.) are detected on the face image in the video, and the face is beautified based on the detected key points. [0003] The existing key point detection methods usually obtain video samples, manually mark the key points of the image samples to be detected in the video samples, obtain the key point detection network based on video sample training, and use the key point detection network to obtain the key points in the video to be detected. The key points of the image to be detected. [0004] However, with existi...
