SnoopIm is a content-based search engine allowing to discover and retrieve small visual patterns or objects in large collections of pictures (such as logos on clothes, road signs in the background, paintings on walls, etc.) and to derive statistics from them (frequency, visual cover, size variations, etc.). Query objects to be searched can be either selected from the indexed collection of photos, or selected from an external picture (by simply providing its URL). The web application allows online search of multiple users and has a cache feature to speed-up the processing of seen queries. It is implemented in Javascript on top of a C++ library developed in collaboration with INA (http://www.ina-sup.com/ ). The software is used at INA by archivists and sociologists in the context of the Transmedia Observatory project.
