Title:
METHOD AND DEVICE FOR TRAINING CUTOUT MODEL AND FOR CUTOUT, EQUIPMENT, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/127454
Kind Code:
A1
Abstract:
A method and device for training a cutout model and for cutout, equipment, and a storage medium, related to the field of computer vision. The method comprises: inputting a sample image into a first image segmentation model and a second image segmentation model to respectively produce an initial sample mask image and an initial sample trimap image corresponding to the sample image; optimizing the initial sample trimap image by utilizing the initial sample mask image to produce a target sample trimap image; inputting the target sample trimap image and the sample image into a cutout model to produce a sample alpha image corresponding to the sample image; and training an image processing model on the basis of the sample alpha image and of a tagged alpha image corresponding to the sample image. This increases the accuracy of segmenting the trimap image, thus increasing the cutout precision and accuracy of the cutout model.
