Inertial sensors such as seismometers, geophones, and accelerometers cannot distinguish horizontal motion from tilt motion. Rotation measurements can be used to subtract the tilt component from horizontal measurements, but the noise in the tilt sensor is often a limiting factor. No mechanism can change the dual sensitivity of inertial sensors to tilt and translation, but the transmission of gro...

In advanced driver assistance systems and autonomous driving vehicles, many computer vision applications rely on knowing the location of the vanishing point on a horizon. The horizontal vanishing point’s location provides important information about driving environments, such as the instantaneous driving direction of roadway, sampling regions of the drivable regions’ image features, and the sea...

Visualization of 3-D volume data through maximum intensity projections (MIP) requires isotropic voxels for generation of undistorted projected images. Unfortunately, due to the inherent scanning geometry, X-ray computed tomographic (CT) images are mostly axial images with submillimeter pixel resolution, with the slice spacing on the order of half to one centimeter. These axial images must be in...

In this paper, we study and analyze the memory reference of deblocking filter in H.264/AVC baseline decoder based on SimpleScalar/ARM simulator. In order to reduce the number of memory references and thus improve overall system performance in an embedded system, we propose an advanced filtering process order with an efficient VLSI architecture which simultaneously processes the horizontal filte...

A method is described of obtaining the relationship between electrical stimulation of the abducens nerve and horizontal eye movement in the dogfish. The stump of the VIth nerve was stimulated intracranially in a fish in which the brain had been removed, but in which the circulation remained intact, and the gills were perfused with sea water. Horizontal rotation of the eye was monitored with an ...

The horizontal visibility algorithm was recently introduced as a mapping between time series and networks. The challenge lies in characterizing the structure of time series (and the processes that generated those series) using the powerful tools of graph theory. Recent works have shown that the visibility graphs inherit several degrees of correlations from their associated series, and therefore...

In this paper, we present two systems that were used for head pose estimation during the CLEAR06 Evaluation. We participated in two tasks: (1) estimating both pan and tilt orientation on synthetic, high resolution head captures, (2) estimating horizontal head orientation only on real seminar recordings that were captured with multiple cameras from different viewing angles. In both systems, we u...

Generally, the color filter array (CFA) image is interpolated considering the correlation between color channels. Previous works first interpolate the green (G) signal, and then obtain the differences between theR/B signal and the reference signal (the initial interpolated G signal). To determine the direction of interpolation, the proposedmethod computes the horizontal/vertical absolute inter-...
