MetricKnn is an open source library to address the problem of similarity search, i.e., to efficiently locate objects that are close to each other according to some distance function. MetricKnn is comprised of:
- Command Line, which is able to perform similarity searches through console commands. Available for Windows and Linux.
- C API, which provides the implementation of different indexes, distances and search methods.
- C++ API, which is a thin C++ wrapper of the C API.
The intended users are software developers, academics, students and data scientist who need to efficiently compare objects according to some criteria.
