In this paper we investigate the relationship between the status and the displacement of a connected weighted graph. We also obtain a product result for the displacements.

Creating descriptors for trajectories has many applications in robotics/human motion analysis and video copy detection. Here, we propose a novel descriptor for 2D trajectories: Histogram of Oriented Displacements (HOD). Each displacement in the trajectory votes with its length in a histogram of orientation angles. 3D trajectories are described by the HOD of their three projections. We use HOD t...

We have been studying coand postseismic displacements from large earthquakes since mid-2006, using ALOS PALSAR images acquired before and after these events. Due to its wavelength, coherence is high even in heavily vegetated areas or steep ranges. We can estimate slip distribution of these earthquakes based on the observed interferograms using a nonlinear inversion scheme. So far, we could not ...

A region in an alternated pair of random-dot patterns was uniiormty displaced. It U:E perceiled ‘1s a segregated. coherently moving shape only if the displacement was smdii. The hmit on the displacement was Its absolute size (maximum about 15’) rather than the number of elements’ widths. Segregation due to apparent motion did not occur if the two patterns were exposed to diKerent eyes. These co...
