In this work, we have designed a local and a global descriptor based on the Stockwell transform. The Stockwell transform time frequency distribution plot possesses a better time frequency resolution than the Gabor transform (the short term Fourier transform (STFT) with a Gaussian window) time frequency distribution. The imaginary part of the Stockwell transform time frequency distribution is found to be robust against illumination variation. Hence it must be possible to design better… CONTINUE READING
