英文摘要

      An effective method of pattern recognition is introduced. It is used in towel and textile fabric making process. For the multi-feature extraction using the fuzzy wavelets intelligent arithmetic and making FWA analysis, it combines fuzzy tools and wavelet transform techniques for providing a robust feature extraction and failure detection and identification scheme. The input signal first undergoes preprocessing and then the features are extracted using the wavelet transform. The extracted features are fuzzified and an inference engine uses the knowledeg-base to declare fault conditions. The fuzzification process adapts dynamically to external disturbances so that the classification performance is continuously improved. The architecture can be used in practical field for feature extraction and defect identification in textile fabric. The detection speed is quickened and real-time operation is satisfied.
