Shape recovery methods from an image sequence have been studied by many researchers. Theoretically, these methods are perfect, but they are sensitive to noise, so that in many practical situations, we could not obtain satisfactory results. In addition, we could not obtain the scale of the recovered object because of the imageprojection property. To solve these problems, we propose a shape recov...

We present a deeply integrated method of exploiting low-cost gyroscopes to improve general purpose feature tracking. Most previous methods use gyroscopes to initialize and bound the search for features. In contrast, we use them to regularize the tracking energy function so that they can directly assist in the tracking of ambiguous and poor-quality features. We demonstrate that our simple techni...

Methods for constructing synthetic multidimensional electron hole equilibria without using particle simulation are investigated. Previous approaches have various limitations and approximations that make them unsuitable within the context of expected velocity diffusion near trapped-passing boundary. An adjustable model distribution function is introduced avoids unphysical singularities there, ye...

This paper presents a novel tri-axial rate gyroscope design. It reviews the physics of the gyroscope and specifies the application domain for the gyro. The design is then presented. It features a unique method of operation; CMOS metal layers are used for sensing and activation for all three axes. This method was previously thought of for sensing z-axis vibrations but not activation of z-axis vi...

Requirements for a gyroscope intended for use in land navigation in a coupled dead-reckoning/GPS are governed more by cost than by performance. As a result, explicit performance measures are poorly defined. The development of a low-cost fiber optic gyro for this application is described. Using openloop signal processing, a short coil length, and simple packaging concepts, it represents an evolu...

This paper pertains to the reduction of measurement errors due to drift in rate gyros used for tracking the position of moving vehicles. In these applications, gyros and odometry are often used to augment GPS when GPS reception is unavailable. Drift in gyros causes the unbounded growth of errors in the estimation of heading, rendering lowcost gyros almost entirely useless in applications that r...
