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