Abstract
The technique of independent component analysis (ICA) in Fourier space is proposed for the detection of base functions, that can be applied both in speech coding and contour-based shape description in digital images. Our aim is to compare our coding scheme with the Mel cepstrum features of speech and the complex contour Fourier features of image contours. The basic advantage of ICA-based features is that they adapt to the available learning samples.
