	att_abstract={{Camera calibration is essential for many applications of computer
vision. However, the process of calibration can be very time
consuming and may require a significant amount of human
intervention. Calibration models traditionally employ a calibration
grid whose four corner points must be marked by hand on a
per-frame basis. Our objective is to develop a technique for
processing these frames rapidly, with as little human intervention
as possible. In this paper, we propose an algorithm to extract the
boundaries of the calibration grid automatically, based on a
spectral analysis of HD (high-definition) video frames. We
compare the accuracy of the intrinsic parameters estimated using
our automatic method with a method that involves hand labeling of
the corner points.}},
