Good lecture on fast motion estimation techniques. I would
be interested in hearing about hierarchical pyramids,
integral projection, and any others I might not even know of
yet.

I am looking to apply parallel computing platforms such as
graphics cards ( via CUDA and OpenCL ) to speed up the
prediction process.
