Snoop is a generalist C++ library dedicated to high-dimensional data management and efficient similarity search. Its main features are dimension reduction, high-dimensional feature vectors hashing, approximate k-nearest neighbors search and Hamming embedding. Snoop is a refactoring of a previous library called PMH developed jointly with the French National Institute of Audiovisual. It is based on the joined research work of Alexis Joly and Olivier Buisson. SnoopIm is a content-based image search engine built on top of Snoop and allowing to retrieve small visual patterns or objects in large collections of pictures. The software is being experimented/used in several contexts including a logo retrieval application set up in collaboration with INA (DigInPix: http://diginpix.ina.fr), a whale's individuals matching application set up in collaboration with CetaMada NGO (IdentyWhale, to be publicly released soon), a hieroglyphs recognition application currently under development in collaboration with the Egyptology department of Montpellier University Paul-Valéry.
