Geometric Coding for Billion-Scale Partial-Duplicate Image Search

Description: The invention leverages geometric coding to encode spatial relationships among local features of images, enabling the retrieval of partial duplicates through global verification. By utilizing geometric square coding and geometric fan coding to create three geo-maps, this approach significantly enhances the detection of duplicate images...
