A template matching approach is used to demosaic (reconstruct) a full color image from the sparse pixel data captured
by a CMOS imager. The proposed method is based on the Nevatia-Babu template-based linear feature extraction
algorithm. This approach provides the color accuracy of gradient based algorithms yet reaps the benefit of regularity of
processing of bilinear interpolation. In this paper we describe the algorithm (gradient estimation and color interpolation),
compare results to other approaches, and present a hardware implementation. The consideration of hardware
implementation is especially important as CMOS imagers find their way into low cost devices such as cell phones and
other novelty camera applications.
Single vehicle roadway departures (SVRD) are serious vehicular accidents that may be avoided through the use of advanced technology. In this paper we briefly describe our Vehicle Lateral Position Measurement System designed to alert the driver of possible SVRD situations. We then describe our testing of the system under a contract awarded by the National Highway Traffic Safety Administration to Rockwell International.
