Abstract
A system for re-ranking retrieved matching images. The system comprises a processor configured to extract at least one QI global feature from query image by global feature extractor module, and extract plurality of QI local features for the query image by local feature extractor module, and then search and retrieve top-k reference images from plurality of reference images based on at least one QI global feature and at least one KRI global feature associated with top-k reference images by filtering module. The processor is configured to perform matching of the plurality of QI local features with the plurality of KRI local features associated with the top-k reference images by fine tuning module and generate matching distance by distance fusion module, wherein the top-k reference images are re-ranked based on the matching distance and generate confidence score for the top-n reference images by confidence score generation module.
