We consider how tracking in stereo may be enhanced by coupling pairs of active contours in different views via affine epipolar geometry and various subsets of planar affine transformations, as well as by implementing temporal constraints imposed by curve rigidity. 3D curve tracking is achieved using a submanifold model, where it is shown how the coupling mechanisms can be decomposed to cater fo...

In our research, people use actions to expose hidden targets as planar images displayed either in situ or ex situ (displaced remotely). We show that because ex situ viewing impedes relating actions to their perceptual consequences, it impairs localizing targets, including compensating for surface deformation, and directing movement toward them. Using a 3D analogue of anorthoscopic perception, w...

An efficient formulation for dynamic analysis of planar Timoshenko’s beam with finite rotations is presented. Both an inertial frame and a rotating frame are introduced to simplify computational manipulation. The kinetic energy of the system is obtained by using the inertial frame so that it takes a quadratic uncoupled form. The rotating frame together with the small strain assumption is employ...

Recently, there has been a large interest in the 3D modeling of real scenes using range data scanned by laser sensors. After the range scans from different viewpoints are acquired, an important step is the registration of these different scans in a common frame of reference. Considering that there often exist a great number of planes in real scenes, we present a range registration method based ...

A straight line drawing of a graph is an open weak rectangle-of-influence (RI) drawing, if there is no vertex in the relative interior of the axis parallel rectangle induced by the end points of each edge. Despite recent interest of the graph drawing community in rectangle-of-influence drawings, no algorithm is known to test whether a graph has a planar open weak RI-drawing, not even for inner ...

introduction: hemangiomas are the most frequent benign tumors of the liver and detecting them from metastasis or other malignant hepatic tumors is of outmost importance. 99mtc- rbc scan is highly specific and is the method of choice for this differentiation. this scintigraphy is performed in planar and spect modes. these two procedures are in agreement most of the times, however since spect is ...

In this paper we present a novel approach for detection of independently moving foreground objects in non-planar scenes captured by a moving camera. We avoid the traditional assumptions that the stationary background of the scene is planar, or that it can be approximated by dominant single or multiple planes, or that the camera used to capture the video is orthographic. Instead we utilize a mul...

a generalization of the known results in fusion frames and $g$-frames theory to continuous fusion frames which defined by m. h. faroughi and r. ahmadi, is presented in this study. continuous resolution of the identity (cri) is introduced, a new family of cri is constructed, and a number of reconstruction formulas are obtained. also, new results are given on the duality of continuous fusion fram...

We present a prototype imaging system that utilizes focal and temporal image space modulation to compress high-frequency, volumetric spatiotemporal information into low-framerate, planar images. 24-frame video sequences and extended depth of field reconstructions from single compressive measurements are reported.
