Diagnostics for Digital Capture Using MTF
The modulation transfer function (MTF) has long been used as a diagnostic tool for analog image capture, by tracking frequency response caused by aperture, field position, or defo...

Randomized motion estimation
Motion estimation is known to be a non-convex optimization problem. This non-convexity comes from several ambiguities in motion estimation such as the aperture problem, or fast mo...
