  • Method and apparatus for automatic recognition using features encoded with product-space vector quantization
    Patent number: 6256607
    Abstract: An automatic recognition system and method divides observation vectors into subvectors and determines a quantization index for the subvectors. Subvector indices can then be transmitted or otherwise stored and used to perform recognition. In a further embodiment, recognition probabilities are determined for subvectors separately and these probabilities are combined to generate probabilities for the observed vectors. An automatic system for assigning bits to subvector indices can be used to improve recognition.
