Welcome to M-Index project
The M-Index is an indexing structure for similarity search in data modeled as generic metric spaces. The M-Index can organize your data collection based on a similarity function (distance) and then quickly evaluate similarity queries like k-nearest neighbors query (give me k indexed objects most similar to this example) or range queries (give me all indexed objects in distance smaller than given radius).
The structure was developed and this project initiazed by the DISA laboratory at Masaryk University, Brno, Czech Republic. This implementation is used in most of demo application of DISA. The package is a Java Maven project containing both centralized M-Index and its distributed version (restricted functionality).
Details on the M-Index structure are described in these papers:
