Various studies show that drowsiness reduces driver alertness and can significantly affect driver performance. In this paper, we investigate the effect of drowsiness on the interaction with the in-vehicle infotainment system (IVIS) while driving. The motivation was to investigate whether a specific type of user interface can provide better performance and lower distraction when the driver is drowsy...
3D movies are calibrated to meet a certain screen brightness standard. Therefore, what would be the consequences on the quality of the 3D experience for spectators watching a 3D movie when movie theaters do not respect this standard? First, we attempted to better understand which factors were important for a spectator by conducting an experiment where participants watched a 3D movie and filled out...
We present an innovative method for detecting interest points (IPs) in grayscale and color images. It is based on the use of angular signatures (ASs), produced by spinning, at each pixel in the image, an "x-tapered, y-derivative, half-Gaussian kernel" in discrete angular steps. By exploiting the AS(s) produced at each pixel, it automatically "classifies" the pixel as being an IP...
Many applications require the use of multiple cameras to cover a large volume. In this paper, we evaluate several pairwise calibration techniques dedicated to multiple range cameras. We compare the precision of a self-calibration technique based on the movement in front of the cameras to object based calibration. While the self-calibration technique is less precise than its counterparts, it yields...
We consider the problem of matching interest points (IPs) extracted from the two images of a stereoscopic pair. We describe each IP via a descriptor consisting in one angular signature for a grayscale image, three signatures for a color image, and, more generally, N signatures for N coregistered images of different modalities. Each angular signature is generated by spinning a “steerable x-tapered,...
