Early Processing in the Human Visual System
These two videos provide an overview of the early processing stages in the human visual system, drawing in part from studies of monkeys whose visual system is very similar to that of humans. The first video takes you from the first stage of sensing light by the photoreceptors in the eye, through the output of the retina generated by the retinal ganglion cells, to the lateral geniculate nucleus (LGN). The second video examines the processing of visual information by so-called simple and complex cells in primary visual cortex. In both videos, connections are made between the early processing that takes place in biological systems and the computations underlying the detection of image intensity changes, or edges, in computer vision systems.
