Histograms of Oriented Optical Flow and Binet-Cauchy Kernels on Nonlinear Dynamical Systems for the Recognition of Human Actions
System theoretic approaches to action recognition model the dynamics of a scene with linear dynamical systems (LDSs) and perform classification using metrics on the space of LDSs, ...

Vector fluid: a vector graphics depiction of surface flow
We present a simple technique for creating fluid silhouettes described with vector graphics, which we call ”Vector Fluid.” In our system, a solid region in the fluid is repr...

Alternative "vision": a haptic and auditory assistive device
We have used two cameras and a SensAble Technologies "Phantom" force-feedback haptic display to haptically render a three-dimensional surface that represents key aspects...

Dimensional Analysis of Image Motion
Studies of image motion typically address motion categories on a case-by-case basis. Examples include a moving point, a moving contour, or a 2D optical flow field. The typical ass...

Anti-geometric diffusion for adaptive thresholding and segmentation
In this paper, we present a novel adaptive thresholding technique based upon an anisotropic diffusionmodel, whichmay be referred to as the anti-geometric heat flow. In contrast to...
