Title:
受動的なオーディオ入力をニューラルネットワークに使用する車両分類システム
Document Type and Number:
Japanese Patent JPH09512339
Kind Code:
A
Abstract:
A system for classifying vehicles based on the sound waved produced by the vehicles receives analog sound pressure levels and converts them to a power spectrum. Fuzzification functions, such as asymmetric wedge shaped functions, are convoluted with the power spectrum to create a vector that characterizes the power spectrum while reducing the dimensionality of the characterizing vector. A neural network analyzes the characterizing vector and produces a classification designator indicative of the class of the object associated with the analog sound pressure levels received by the system.
