Several models have been proposed for how the brain measures velocity from the output of motion-energy units. These models make some unrealistic assumptions such as the use of Gabor-shaped temporal filters, which are non causal, or flat spatial spectra, which are invalidated by existing data. We present a Bayesian model of velocity perception, which makes(More)

However, it mostly misses the point of what open source means to a development organization. In this article, I use the experiences of GizmoSoft (a(More)
