ACTIVE VISUAL PERCEPTION METHOD AND DEVICE FOR CHARACTERISATION AND RECOGNITION THROUGH THE ANALYSIS OF MONO/MULTIDIMENSIONAL PARAMETERS IN MULTICLASS COMPUTING UNITS AND HISTOGRAM PROCESSING, DYNAMIC UNIT RECRUITMENT

摘要

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.
