Non-Parametric Blur Map Regression for Depth of Field Extension
—Real camera systems have a limited depth of field (DOF) which may cause an image to be degraded due to visible misfocus or too shallow DOF. In this paper, we present a blind de...

Texture-Independent Long-Term Tracking Using Virtual Corners
—Long term tracking of an object, given only a single instance in an initial frame, remains an open problem. We propose a visual tracking algorithm, robust to many of the diffic...
