In the isolated word speech recognition system, the extraction and matching of the characteristic parameters is the key link. This paper introduces a new feature parameter extracting methods on basis of Pulse Coupled Neural Network (PCNN) for the recognition system. By means of the visibility of speech spectrogram, the PCNN is used to extract the time series and entropy series from the spectrogram...
Foreground object extraction, which aims to accurately separate a foreground object from its background in still images, plays an important role in many computer vision applications. An interactive object extraction method by extending the graph cut approach is presented in this paper. The coarse-to-fine object segmentation method makes it efficiently to specify the main object and adjust the detail...
This paper introduces the basic theory of speech recognition, including speech signal pre-emphasis, endpoint detection and feature extraction, pattern recognition. On this basis, we introduce the MFCC (Mel-frequency cepstral coefficients) specific extraction method. Secondly, from the recognition rate and improve the speed of approach to identify proposed DTW (dynamic time warping) algorithm to improve...
Although Kernel Principle Component Analysis(KPCA)has been used to monitoring nonlinear processes, it is not well suited for fault diagnosis. In order to solve this problem, a new method of fault detection and diagnosis for nonlinear processes based on KPCA and Least Squares Support Vector Machine(LSSVM) is proposed. The KPCA is used to monitor faults and extract feature and LSSVM model is used to...
