Embodiment Construction

[0032] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only some structures related to the present application are shown in the drawings but not all structures.

[0033] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processing, many of the steps may be performed in parallel, concurrently, or simultaneously. Additionally, the order of steps may be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The ...

Abstract

The embodiment of the application discloses a training method, a matting method, a device, a medium and a terminal of an image processing model. The training method of the image processing model includes obtaining a trichotomy of the original image; Generating a training sample set according to the original image and the trichotomy; The preset depth learning network is trained based on the training sample set to obtain an image processing model, wherein, the image processing model is used for labeling the original image to obtain a trichotomy. By adopting the technical proposal, the input original image can be automatically annotated to obtain a trichotomy, and a large amount of hairline level data annotation can be carried out without manual annotation, the annotation workload can be reduced, and the image annotation efficiency can be improved. In addition, the matting effect can be optimized by using image processing model to label the original image, avoiding the error that may be introduced by manual labeling.

Description

technical field [0001] The embodiments of the present application relate to image processing technologies, and in particular to a training method for an image processing model, a map matting method, a device, a medium, and a terminal. Background technique [0002] At present, image matting has become one of the most commonly performed operations in image processing. For example, more and more people choose to buy clothes on the Internet, so the function of searching for things by pictures of e-commerce came into being. It is very difficult to accurately search for similar clothing, so it is necessary to segment the portraits in the picture. For another example, the realization of some portrait beautification functions also depends on the precise segmentation of background and portrait. [0003] The matting scheme in the related art is mainly based on pixel clustering methods and algorithms such as "Graph Partitioning" (GraphPartitioning) algorithms. This type of method is ...
