Title:
MASK-GUIDED IMAGE MOSAIC LINE GENERATION METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/016368
Kind Code:
A1
Abstract:
A mask-guided image mosaic line generation method and apparatus, a computer device, and a storage medium. The method comprises: generating a mask image file and an initial mosaic-line raster file; computing the positions of image ranges of images to be mosaicked, which positions are in the mask image file, and generating a marked image file of each of said images; according to a mask intersection of any two of said images that have an intersection therebetween, dividing said images and updating the mosaic-line raster file; assigning a pixel value to each pixel in the mosaic-line raster file until the traversal of all intersecting images is completed; and vectorizing the mosaic-line raster file, so as to generate a mosaic-line vector file. The method improves the efficiency and precision of image mosaic line generation.
