Abstract

The invention belongs to the fields of image recognition, segmentation, map-out and virtual data generation, and in particular relates to the automatic map-out of hand motion blur and its application in soft segmentation and background replacement of the human body, and aims to solve the problem that the automatic map-out effect of the motion-blurred hand is not good. And the problem of inability to obtain a large number of labeled motion blur matting training data. The method of the invention includes: using a hand motion blur automatic matting network to automatically matte the acquired motion blurred hand image, obtaining a hand matting alpha result map and outputting; wherein, the hand motion blur automatic matting network The training samples are obtained by the virtual image generation method. On the one hand, when the human hand in the image has severe motion blur, the present invention can still accurately cut out the human body and switch the background, bringing the user an excellent immersive experience; on the other hand, the method for generating a virtual motion blurred hand image can A large amount of virtual data is generated in a short time, which effectively solves the problems of insufficient training samples and difficulty in labeling the true value.

Description

technical field [0001] The invention belongs to the fields of image recognition, segmentation, matting and virtual data generation, and specifically relates to automatic matting of hand motion blur and its application in human body soft segmentation and background replacement. Background technique [0002] Nowadays, more and more people like to use video to communicate, such as: video chat, video conference, online classroom and so on. Human body segmentation technology can help people replace the background in the video, so as to make the video communication more vivid and interesting, and also enable users to have a better immersive experience. In addition, accurate human body segmentation is also of great significance for further human behavior analysis. However, existing segmentation methods are mainly aimed at clear images, and when people use video to communicate, they often use gesture language. At this time, hand movements are rapid, which causes motion blur. Accur...
