1. A computer-implemented method of encoding a given image in a series of images, the method being performed by one or more processors configured to execute computer program modules, the method comprising: obtaining a scaled image by scaling the given image using a statistical parameter that is based on one or more images preceding the given image in the series of images; obtaining a generator signal by applying a spatiotemporal filter to the scaled image, the generator signal conveying information associated with one or both of a spatial change or a temporal change between the given image and one or more images preceding the given image in the series of images; and providing a pulse signal comprising one or more digital pulses based on the generator signal such that a temporal latency associated with individual pulses encodes one or both of the spatial change or the temporal change conveyed by the generator signal, the temporal latency being based on the scaled image associated with the one or more images preceding the given image in the series of images.
