Where Have I Been in Warsaw? Finding Answers Through Image Matching Algorithm
Use a pair matching algorithm to locate where you have been in Warsaw by comparing an unknown picture with a geotagged reference database. The architecture and landscapes of Warsaw can provide clues, and a CDVS database can assist in identifying locations. Access the CDVS Web Service, library, and GSW scraper to enhance your search. The process involves querying the database, mapping the results, and analyzing observations. The aim is to make this service public and improve performance while considering future developments. Explore the possibilities of open-sourcing the REST API and the CDVS.js for a seamless experience.
