This paper presents an application of the quaternion Fourier transform for the preprocessing for neural-computing. In a new way the 1D acoustic signals of French spoken words are represented as 2D signals in the frequency and time domain. These kind of images are then convolved in the quaternion Fourier domain with a quaternion Gabor filter for the(More)
The principle of a vision system based on a progressive focus of attention principle is presented. This approach considers the visual recognition strategy as an estimation problem for which the purpose is to estimate both precisely and reliably the parameters of the object to be recognized. The object is constituted of parts statistically dependent one each(More)
