Title:
IMAGE SEGMENTATION-BASED TEXT POSITIONING METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/051527
Kind Code:
A1
Abstract:
An image segmentation-based text positioning method, apparatus and device, and a storage medium, relating to the field of artificial intelligence. Said method comprises: acquiring an original image, the original image being a ticket image or a certificate image which is acquired under a text background (101); performing image segmentation on the original image by means of a preset image segmentation network model, so as to obtain a distorted image, the distorted image being the ticket image or the certificate image (102); performing affine transformation on the distorted image to obtain a distortion-corrected image, the text in the distortion-corrected image being text in a forward direction (103); and performing text positioning on the distortion-corrected image, so as to obtain a positioning result (104). Image segmentation network processing is performed on an image under a complex text background, so as to obtain an accurate image foreground image, and text positioning processing is performed on the image foreground image, so as to obtain a positioning result, so that the accuracy of image text positioning is improved, and the robustness of the complex background is enhanced.
