METHOD FOR OPTIMIZING DECOMPOSITION OF AN ASYNCHRONOUS SIGNAL

摘要

The present invention relates to a method for optimizing the decomposition of an asynchronous signal (104) produced by a light sensor. The method comprises: / a / obtaining a decomposition (301) of said signal on the basis of decomposition; / b / receiving the asynchronous signal comprising at least one event (302), the at least one event having been generated by the sensor between the first time and a second subsequent time; / c / determining (303a) a first value of said pixel (x (l, c)) for the first beat; / d / determining (303b) a second value of said pixel (x (l, c)) for the second beat; / e / determining an update of the decomposition (308) obtained as a function of said obtained decomposition, of a difference between the first value and of the second value and of a term (El, c) function of coordinates of said pixel (l, c) and the decomposition base of said transformation.
