Toward Wide-Angle Microvision Sensors
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Sanjeev J. Koppal,Ioannis Gkioulekas,Travis Young, Hyunsung Park,Kenneth B. Crozier,Geoffrey L. Barrows,Todd Zickler
Issue Date:December 2013
pp. 2982-2996
Achieving computer vision on microscale devices is a challenge. On these platforms, the power and mass constraints are severe enough for even the most common computations (matrix manipulations, convolution, etc.) to be difficult. This paper proposes and an...
 
Appearance Derivatives for Isonormal Clustering of Scenes
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Sanjeev J. Koppal, Srinivasa G. Narasimhan
Issue Date:August 2009
pp. 1375-1385
A new technique is proposed for scene analysis, called
 
Novel Depth Cues from Uncalibrated Near-field Lighting
Found in: Computer Vision, IEEE International Conference on
By Sanjeev J. Koppal, Srinivasa G. Narasimhan
Issue Date:October 2007
pp. 1-8
We present the first method to compute depth cues from images taken solely under uncalibrated near point lighting. A stationary scene is illuminated by a point source that is moved approximately along a line or in a plane. We observe the brightness profile...
 
Structured Light in Scattering Media
Found in: Computer Vision, IEEE International Conference on
By Srinivasa G. Narasimhan, Shree K. Nayar, Bo Sun, Sanjeev J. Koppal
Issue Date:October 2005
pp. 420-427
Virtually all structured light methods assume that the scene and the sources are immersed in pure air and that light is neither scattered nor absorbed. Recently, however, structured lighting has found growing application in underwater and aerial imaging, w...

By Sanjeev J. Koppal, Srinivasa G. Narasimhan
Issue Date:June 2006
pp. 1323-1330
We propose a new approach called
