Document Type and Number:
WIPO Patent Application WO/2022/033513
Kind Code:
A1
Abstract:
The present application is applicable to the field of image processing. Provided are a target segmentation method and apparatus, and a computer-readable storage medium and a computer device. The method comprises: obtaining a first target frame in a target image by using a preset target acquisition model; enlarging the first target frame according to a first preset proportion, so as to obtain an enlarged first target frame; by using a preset target segmentation model, processing an image area corresponding to the enlarged first target frame, so as to obtain a mask image after target segmentation, and a second target frame located in the mask image after target segmentation; mapping the mask image after target segmentation to the size of a target image, so as to obtain a first mask image of the target image; and enlarging the second target frame according to a second preset proportion, so as to obtain an enlarged second target frame, and fusing an image corresponding to the enlarged second target frame with the first mask image, so as to obtain a second mask image of the target image. The present application facilitates correcting a wrongly segmented pixel outside a target instance, thereby improving the accuracy of target segmentation.
