Abstract
A method and device for detecting the key point of an image. The method includes acquiring the image, performing preprocessing to generate a multi-channel image with a specific type, and inputting the image into a detection model. The detection model includes a regression branch and an inter-frame residual branch. If the image type is the discrete frame, the system determines coordinates of multiple key points in the image based on a regression prediction value outputted by the regression branch. If the image type is continuous frame, the system determines coordinates of multiple key points in the image based on a regression prediction value outputted by the regression branch and a residual prediction value outputted by the inter-frame residual branch. The method can be used in the detection of discrete frame and discrete frame type images and can improve the stability of key point detection of images.
