Embodiments of the present invention provide a matting model training method, device and system, an image matting method, device and system, and a storage medium. The matting model training method includes: obtaining a sample image and corresponding annotation data, the annotation data is used to indicate the position of the target object in the sample image; determining the object edge area of the target object in the sample image according to the annotation data; according to the object in the sample image The sampling weights assigned to the edge area and other areas in the sample image are used to sample the pixels in the sample image; and the loss function used to train the matting model is calculated according to the sampled pixels, and the loss function, sample image and label data are used to pair matting model for training. The matting model training method is conducive to improving the prediction accuracy of the matting model for object edges, and can greatly improve the user experience of related applications.
Description
Technical field [0001] The present invention relates to the field of image processing, and more particularly to a key model training method, apparatus, and system, and an image kick-like method, device, and system, and storage medium. Background technique [0002] The existing keying technology has an edge blur. For example, humanoid models have a wide range of applications in the fields of live video, and its purpose is to separate the environmental segmentation of portraits and backgrounds, and add specific special effects on this basis to achieve better display and entertainment. The existing human-shaped kick-like system is difficult to solve the fuzzy phenomenon of object edges, and give the user a bad experience. Inventive content [0003] The present invention is proposed in consideration of the above problems. The present invention provides a kayaking model training method, a device, and a system, and an image kick-like method, device, and system, and a storage medium. ...
