2. Studies on continuous and line spectrum extraction in 11/2 - dimensionalSpectrum, and extracting feature parameters in virtue of adaptive wavelet-based neural network, which can be applied to ship target classification and recognition simultaneously.
Owing to the particular advantages of Random Field texture models in aspect of analyzing texture, the paper establishes Markov Random Field texture model to extract the feature parameters of workpiece surface texture images.
In the data collection method of vehicle classification system, this paper proposes the method that utilize 4 copolymer-piezoelectric-axis-sensors to make up the sensor array to get the vehicle type feature parameters, and utilizes that method may obtain attaining 11 vehicle of type feature parameters , and resolve the problem of distinguish to two vehicles running very close.
The identification experiments on 30 speakers including 18 males and 12 females show that MIM model has better performance with the identification error rate of 1.33% if LPCC was used as feature parameters.
A new method was developed to extract the feature parameters of the wear particle image according to the consistency in multi-scale analysis and self-similarity in both wavelet transform and fractal theory.
There are many feature parameters in the polishing powder, such as the distribution of the particles size, the size of crystalline grain and the appearances of polishing powder, which have an influence on the quality of the
3. The signal of instant vibration testing for soil compactness is analyzed both in time domain and frequency domain. Some feature parameters reflecting the characteristics of the signal are extracted.
