The physical justification of pattern recognition with a phaseonly match filter is analysed in this paper. In the experiment the amplitude of Fourier transform of object is modified to reduce the intensity dynamic range, while phase information is preserved. The holographic match filter was made by dichromatic gelation. The high emeiency correlation is obtained by using this method.

The speaker's feature vectors are represented by the long-term averaged vector sequencies of the LPC reflecting coefficients estimated by the Maximum Entropy Spectral Estimation method from the speech. The average within the speaker varince function, the average between the speaker varince function and theratial of average between-within the speaker varince function are defined...

A method of realtime extraction and 3-dimension display of a speaker's features from text-unconfined continuous speech is pressnted. The speaker's feature vectors are represented by the long-term averaged vector sequencies of the LPC reflecting coefficients estimated by the Maximum Entropy Spectral Estimation method from the speech. The average within the speaker varince function, the average between the speaker varince function and theratial of average between-within the speaker varince function are defined and used to analyze the discrimination of the speaker's features.The 3-dimension display of the feature vectors is implemented with the principal of pseudocolor encoding. A master-slaver system with IBM-PC/AT and TMS32010 is designed, which leads to the data sampling and parameter estimating syneh-ronicaily. The result shows that the features are well discriminative and the display is good in readability, visual analysis and whole observation.
