APPARATUS AND METHOD FOR PATTERN RECOGNITION USING MATCHING PURSUIT ALGORITHM

摘要

The present invention provides a device for recognizing a pattern using the matching pursuit algorithm and a method thereof. According to the present invention, in the device for recognizing a pattern using the matching pursuit algorithm, a sliding window divides a received input signal into frame sequences delivers the frame sequences; a matching pursuit feature extraction unit extracts a feature vector using the matching pursuit algorithm from the received frame sequences and delivers the feature vector; a parameter storage unit stores a received parameter and delivers the parameter according to a received request; a feature classification unit generates a parameter for an input signal using the hidden Markov model based on the received feature vector and the stored parameter received from the parameter storage unit and attaches a data label to the generated parameter for identification.
