The perception of coherent motion in two-dimensional patterns (abstract only)
Edward H. Adelson, J. Anthony Movshon · ACM SIGGRAPH Computer Graphics · 1984
When one looks at a two-dimensional scene of moving objects, one can usually assign a velocity to each point in that scene with little effort. This suggests that some early visual processes are able to generate a two-dimensional velocity map using fast parallel computations. But it is not obvious how this should be done, and we are currently trying to understand how the human visual system does it.
