Abstract

Claims (14)

1 . A computer-implemented method comprising:

receiving an input sequence;

extracting a set of features from the input sequence;

determining a frequency distribution for the input sequence based on the extracted features;

restoring time domain information for the input sequence by performing an inverse fast Fourier transformation on the frequency distribution;

augmenting data for the input sequence by decoding the restored time domain information; and

classifying the input sequence based on the augmented data.

2 . The computer-implemented method of claim 1 , in which a full input sequence is restored.

3 . The computer-implemented method of claim 2 , in which the full input sequence is restored based at least in part on an average sample dropping ratio for the input sequence.

4 . The computer-implemented method of claim 1 , further comprising restoring an order of the input sequence.

5 . The computer-implemented method of claim 1 , in which the input sequence comprises a sequence of range-Doppler images.

6 . The computer-implemented method of claim 5 , in which the range-Doppler images correspond to one or more hand gestures.

7 . The computer-implemented method of claim 1 , further comprising determining a length of a cycle of the input sequence.

8 . The computer-implemented method of claim 1 , further comprising extracting at least one noise portion from the input sequence.
