An adaptive version of the integrate and fire-at-threshold model for the neural coding process is presented. The encoder transforms stimulus intensity information into sequences of identical membrane depolarization spikes, their times of occurrence defining a modulated point process. Several theoretical decoding schemes are then introduced and their(More)
Fig. 13. A British WWII Supermarine Spitfire fighter plane featuring a dangerous fiducial. A set of C concentric circles with r1 = 1+1=2C 2 and 1r = 1+1=2C is expected to be a very good (although suboptimal) location shape. Experimental tests in [13] and further theoretical developments recently published in [14], led to the conclusion that the " bull's-eye(More)
time-varying 2D projection. Hence as an intermediate The use of color images for motion estimation is investigated stage in the 3D motion estimation process we need to in this work. Beyond the straightforward approach of using find the 2D projection of a motion field onto the image the color components as separate images of the same scene, a plane. This 2D(More)
Methods of analysis for some deterministic and stochastic variants of the integrate-to-threshold neural coding scheme are presented. Adaptation phenomena are modeled by means of feedforward and feedback adaptive threshold control. Simulations of sinusoidal and step responses reproduce satisfactorily the qualitative characteristics of adaptation as compared(More)
