Abstract: Method (10), in a system for aiding the guidance of a vehicle, for identifying marking stripes of road lanes comprising the phases of subjecting a road image to a convolution operation (14) with a mask matrix so as to identify discontinuities present in the image, comparing the result with a threshold value (16) and determining (18) a representation of the marking stripes, in which the mask matrix is set in such a way as to eliminate at least partially the discontinuities which do not correspond to the marking stripes.

Abstract: A neural network (1) including a number of synaptic weighting elements (15, 17), and a neuron stage (5); each of the synaptic weighting elements (15, 17) having a respective synaptic input connection (11, 13) supplied with a respective input signal (x1, ..., xn); and the neuron stage (5) having inputs (36, 37) connected to the synaptic weighting elements, and being connected to an output (39) of the neural network (1) supplying a digital output signal (O). The synaptic weighting elements (15, 17) are formed by memory cells programmable to different threshold voltage levels, so that each presents a respective programmable conductance; and the neuron stage (5) provides for measuring conductance (33-35, 43-45) on the basis of the current through the memory cells, and for generating a binary output signal on the basis of the total conductance of the synaptic elements.
