This puts forward higher requirements on the efficiency of character action recognition in videos. However, when related technologies use machine learning models to identify some actions from videos, the cost of building neural networks is too high, and the training of machine learning models takes a long time. Long, it is difficult to apply to the requirements of character action recognition in real-time video. At the same time, in related technologies, cartoon stickers are placed on fixed feature points of human body movements to be detected, which cannot achieve the effect of stickers deforming with changes in the user's limbs; It is not conducive to timely and accurate conversion of user actions into corresponding cartoon image changes

The invention provides an image processing method, which comprises the steps of extracting a to-be-detected image in a target video, the to-be-detected image comprising at least two continuous framesof images; determining a target detection area in the to-be-detected image and to-be-detected feature points in the target detection area; detecting the motion state of the to-be-detected feature point to determine a deformation parameter of the to-be-detected feature point; determining deformation parameters of a cartoon image corresponding to the deformation parameters of the to-be-detected feature points according to the deformation parameters of the to-be-detected feature points to form a deformed cartoon image; and fusing the deformed cartoon image and the target detection area machine toform a new image frame which comprises the deformed cartoon image. The invention further provides an image processing device and a storage medium.
Description
technical field [0001] The present disclosure relates to image processing technology in video, and in particular, to an image processing method, device and storage medium. Background technique [0002] In the process of video shooting, users often make various actions in front of the camera to convert them into corresponding cartoon images to increase the sense of fun and interactivity. This puts forward higher requirements on the efficiency of character action recognition in videos. However, when related technologies use machine learning models to identify some actions from videos, the cost of building neural networks is too high, and the training of machine learning models takes a long time. Long, it is difficult to apply to the requirements of character action recognition in real-time video. At the same time, in related technologies, cartoon stickers are placed on the fixed feature points of human actions to be detected, which cannot achieve the effect of stickers deformi...
