In this paper, we propose a system that displays digital documents on real paper surface with arbitrary shape, so that the viewer can feel as if the digital document images are printed on the real paper surface. Such displaying of the digital documents is realized by rendering the document images on the arbitrary shaped surface via a projector. We apply a homography between a source image plane...

Shape analysis of simple closed plane curves is an important subject including many chances of application to industry, especially when the curves are apparent contours of objects projected into the plane. A notion of panorama view is introduced, with presentations of some ideas of its application to the subject.

Ultrasound imaging techniques are proposed for measuring the shape and thickness of immersed waste particles (10-20 mm size) using a linear sensor array from a fixed position. For these purposes both the front and back surface of a particle needs to be reconstructed. Raw ultrasound pulse-echo and plane wave datasets and different imaging techniques were investigated in a case study using a sing...

We present a method that deforms an image plane to visually meet the shape and pose of a manifold surface. The user provides constraints that couple a small number of surface points with their corresponding image pixels to initially deform the plane. Matching, based on geodesic distances, couples additional points, followed by a second deformation that brings the image plane into its final pose...

We present fully nonlinear time-dependent simulations of a thin liquid film flowing down an inclined plane. Within the lubrication approximation, and assuming complete wetting, we find that varying the inclination angle considerably modifies the shape of the emerging patterns: Finger-shaped patterns result for the flow down a vertical plane, while saw-tooth patterns develop for the flows down a...

This paper reports the development of a vision system to automatically classify work-pieces with respect to their shape and color together with determining their location for manipulation by an in-house developed pick-and-place robot from its work-plane. The visionbased pick-and-place robot has been developed as part of a smart flexible manufacturing system for unloading work-pieces for drillin...

In this paper, a compact micro strip fed dome shape slot antenna for Ultra Wide Band (UWB) applications is proposed. The dome shape is obtained by rounding (blending) the corners of a hexagonal slot. To excite the slot, a micro strip feed and a rectangular shape tuning stub is used. One of the corners of the rectangular patch is chamfered while the others are blended for better impedance matchi...

We present a new coordinated control law for a group of vehicles in the plane that stabilizes an arbitrary desired group shape. The control law is derived for an arbitrary shape using models of tensegrity structures which are spatial networks of interconnected struts and cables. The symmetries in the coupled system and the energy-momentum method are used to investigate stability of relative equ...

The paper describes a method for recovering the 3-D shape of a moving object from a sequence of images. While following the motion of the object, a 3-D surface model, initialised to be spherical, progressively deforms itself under the action of simulated external forces applied to the model to drive its profile towards the object profile extracted from the image. An internal energy coupled to t...

The stress singularity of a sharp wedge contacting a frictionless half plane can be avoided by changing the wedge shape. Shape optimization is accomplished with the geometric strain method (GSM), an optimality criterion method. Several numerical examples are provided for different materials in the wedge and half plane to avoid stress singularity near the sharp corner of the wedge. Optimum wedge...
