WebJul 21, 2024 · The highest recognition rate of 98.6 \( \pm \) 0.6 % has resulted in DWT features at level 2. This was substantiated by the fact that DWT features at level 2 establish maximum correlation with pre-processed EEG. Experimental result shows that time-frequency is the best performing feature domain among the three. Further, correlation … WebDCT features have been used for the recognition of face and some coefficients are selected to form feature vectors .

Web1 Answer. Four features is a very short description for an audio signal. The hint: "Write a program to transform an audio track to time-frequency domain" is important. Since audio signals are in general not fully stationary, windowed-Fourier or Short-term Fourier transforms can be important. WebThe CT features achieved classification accuracy of 98.43 whereas the accuracy resulted from DWT features is 96.93. The statistical analysis and ROC curves show that methods based on LBP, statistical measures and CT performs equally well and they not only outperform DWT based method but also other existing methods.
