A Mean Eigenwindow Method for Partially Occluded/Destroyed Objects Recognition

This paper describes a method for recognizing partially occluded and/or destroyed objects using an eigenspace method referred to as a ‘mean eigenwindow’ method that stores multiple partially occluded/destroyed objects in an eigenspace. We have proposed to store similar poses, that may include disturbed shapes, of an object in a particular window referred to as the ‘eigen window’ and, finally, m...

Batting Flying Objects to a Target

This paper presents a planning algorithm for a 2DOF robotic arm to bat flying 2D objects to a targeted location. Impact dynamics are combined with trajectory kinematics and manipulator dynamics to compute the evolving set of states (poses and motions) of the arm able to achieve the task as the object is flying. Planning is conducted under the arm’s dynamic and kinematic constraints. At the time...

Identification of partly destroyed objects using deformable templates

This article addresses the problem of identification of partly destroyed human melanoma cancer cells in confocal microscopy imaging. Complete cancer cells are nearly circular and most of them have a nearly homogeneous boundary and interior region. A deformable template (Grenander, 1993) is well suited for these complete cells and models a cell as a natural deformed template or prototype. We wil...

Oscillations of a Giant Solar Tornado

Solar magnetic tornadoes are known to be one of the mass and energy transport mechanisms from the lower solar atmosphere into the upper layers of the solar corona. A bright spiral structure with two arms is observed using high-cadence EUV images of 171, 193 and 304 Ǻ channels of Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO) on 10th of July 2011 for three hours. ...
