Extracting depth information from pairs of stereo images in real-time allows interactive 3d operations on live video streams. We present a novel adaptation of the Semi-Global Matching (SGM) Algorithm [Hirschmüller 2005] to graphics processing (GPU) hardware, which operates in real-time and frees the CPU for other tasks. We also present shaders which(More)
Recently, there has been great interest in multi-touch interfaces. Such devices have taken the form of camera-based systems such as Microsoft Surface [de los Reyes et al. 2007] and Perceptive Pixel's FTIR Display [Han 2005] as well as hand-held devices using capacitive sensors such as the Apple iPhone [Jobs et al. 2008]. However, optical systems are(More)
Recently, there has been great interest in multi-touch interfaces. These have taken the form of optical systems such as Microsoft Surface and Perceptive Pixel's FTIR display as well as hand-held devices using capacitive sensors such as the Apple iPhone. However, optical systems are inherently bulky while capacitive systems are only practical in small form(More)
Normal mapping uses normal perturbations stored in a texture to give objects a more geometrically complex appearance without increasing the number of geometric primitives. Standard bi-and trilinear interpolation of normal maps works well if the normal field is continuous, but may result in visible artifacts in the areas where the field is discontinuous,(More)
Multi-touch input has been an active area of research for over two decades but has always suffered from the absence of an easily available high quality touch input device. For this reason, exciting user interfaces developed in the lab have appeared on CNN, but not on everyone's desk, computer screens, table-tops, walls and floors. What has been needed - and(More)
Acknowledgments First of all, I must thank my advisor Denis Zorin under whose guidance I have learned how to conduct rigorous computer science research. Denis's knowledge is vast, and his opinions are measured. His curriculum extended beyond computer science and mathematics into life, public policy, and common sense. During my time at NYU, I have been lucky(More)
Dedication To my beautiful daughter Lilu, who reminded me of the incredible wonders possible in this universe and gave me the motivation I needed to get reinstated into the graduate program at NYU and complete my dissertation. iii Acknowledgments I would like to thank New York University, the Graduate School of Arts and Sciences, the Courant Institute and(More)
