The CoPhIR (Content-based Photo Image Retrieval) Test-Collection has been developed to make significant tests on the scalability of the SAPIR project infrastructure (SAPIR: Search In Audio Visual Content Using Peer-to-peer IR) for similarity search.

CoPhIR is now available to the research community to try and compare different indexing technologies for similarity search, with scalability being the key issue.

The organizations (universities, research labs, etc.) interested in building experimentations on it should sign the enclosed CoPhIR Access Agreement and the CoPhIR Access Registration Form, sending the original signed documents to us by mail. Please follow the instruction in the section “How to get CoPhIR Test Collection”. You will then receive Login and Password to download the required files.
