Abstract

The invention relates to an active visual perception device and method employing spatial resolution variation in order to characterise and recognise an object, particularly for identification and position-finding purposes. The object is represented as a series of sequences and sub-sequences of a digital signal. The inventive method consists in performing the following steps over a period of several sequences: a Gaussian time variation in relation to the spatial resolution of the object in said signal, the variation comprising a phase whereby the resolution is increased from a reduced value to an optimum base value; differentiation with smoothing during the variation in order to obtain a signal that is representative of the variability of the difference of Gaussians when a threshold is exceeded; and deducing therefrom prioritised details that can be represented in the form of a parse tree of the object. The aforementioned variation can be produced mechanically or by means of electronic filtering. The invention also relates to multiclass mono- and multidimensional histogram processing and computing modules that can be dynamically recruited.
