Robust Software for Computing Camera Motion Parameters - Schreiber, Robert; Li, Zeyu; Baker, Harlyn
Keyword(s): camera, motion, parameters
Abstract: We revisit the method of Tsai, Huang, and Zhu for the computation of camera motion parameters in computer vision. We elucidate some spectral properties of the homography matrices that arise, which are rank-one perturbations of rotation matrices. We show how to correct for noise by finding the rank-o ...

FreePad: A Novel Handwriting-based Text Input for Pen and Touch Interfaces - A., Bharath; Madhvanath, Sriganesh
Keyword(s): text input, pen and touch interfaces, handwriting recognition, freepad
Abstract: The last decade has seen tremendous growth in mobile devices such as Pocket PCs, mobile phones, Tablet PCs and notebooks. Most of these devices enable interaction through a stylus or touch interface, powered by handwriting recognition (HWR) capability. In this paper, we propose a novel input method ...

Peer-to-peer Ink Messaging across Heterogeneous Devices and Platforms - Prasad A, Manoj; Selvaraj, Muthuselvam; Madhvanath, Sriganesh
Keyword(s): Digital Ink Markup Language, Ink Messaging, XMPP
Abstract: Pen and touch interfaces for personal and shared devices are becoming increasingly relevant today, in the context of mobility and ease of use. A key capability enabled by pen-interfaces is that of messaging using handwritten, as opposed to text messages. Not only are ink messages easier to enter tha ...
