`1[pre]
`
`
`1[pre.a] A visual perception processor for automatically detecting an event
`occurring in a multidimensional space (i, j) evolving over time
`
`1[pre.b] with respect to at least one digitized parameter in the form of a
`digital signal on a data bus,
`
`1[pre.c] said digital signal being in the form of a succession aijT of binary
`numbers associated with synchronization signals enabling to define a given
`instant (T) of the multidimensional space and the position (i, j) in this space,
`the visual perception processor comprising:
`
`
`1[a] the data bus;
`
`1[b] a control unit;
`
`1[c] a time coincidences bus carrying at least a time coincidence signal; and
`
`1[d] at least two histogram calculation units for the treatment of the at least one
`parameter,
`
`1[e] the histogram calculation units being configured to form a histogram
`representative of the parameter as a function of a validation signal and to
`determine by classification a binary classification signal resulting from a
`comparison of the parameter and a selection criterion C,
`
`1[f] wherein the classification signal is sent to the time coincidences bus,
`and wherein the validation signal is produced from time coincidences signals
`from the time coincidence bus so that the calculation of the histogram
`depends on the classification signals carried by the time coincidence bus.
