Abstract
A device for compressing a feature descriptor includes a non-uniform quantizer and a run-length encoder. The non-uniform quantizer accesses a source feature descriptor from a storage device, and non-uniformly quantizes the source feature descriptor having source vectors into an intermediate feature descriptor having intermediate vectors according to a vector default value. The run-length encoder executes run-length coding for the intermediate feature descriptor to generate a compressed feature descriptor.
