In this paper we describe a method for 3D body scanning by aligning depth and color scans which were taken around a human body with a Kinect camera. The Kinect [18] camera is a “controller-free gaming and entertainment experience” by Microsoft for the Xbox 360 video game platform. It delivers depth and color scans at video rate. The proposed scanning solution makes 3D scanning technology more a...

We are studying the geometry of a 360 x 360 mosaic image formation. A 360 x 360 mosaic camera model and a calibration procedure are proposed. It is shown that only one point correspondence is needed in order to acquire epipolarily rectified images. The 360 x 360 mosaic camera model is therefore determined by only one intrinsic parameter. It is shown that the relation between coordinates estimat...

It is shown that the two-loop Kac-Moody algebra is equivalent to a two variable loop algebra and a decoupled β-γ system. Similarly WZNW and CSW models having as algebraic structure the Kac-Moody algebra are equivalent to an infinity of versions of the corresponding ordinary models and decoupled abelian fields.

How readily do potential migrants respond to increased returns to migration? Even if origin areas become less attractive vis-à-vis migration destinations, fixed costs can prevent increased migration. We examine migration responses to hurricanes, which reduce the attractiveness of origin locations. Restricted-access U.S. Census data allows precise migration measures and analysis of more migrant-...
