1. A neuromorphic vision system generating and processing image data, the system comprising: an image sensor comprising a plurality of photoreceptors each generating image data for generation of spike data, wherein spike data indicates whether an intensity value measured by that photoreceptor exceeds a threshold; and means for generating the spike data based on image data generated by the plurality of photoreceptors, the means for generating the spike data comprising a plurality of computational elements corresponding to the plurality of photoreceptors of the image sensor, wherein each of the plurality of computational elements generates spike data for the respective corresponding photoreceptor based on the image data generated by at least two of the plurality of photoreceptors, wherein the at least two of the plurality of photoreceptors includes the respective corresponding photoreceptor and a photoreceptor neighboring the respective corresponding photoreceptor.
