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...
Inverse volume rendering with material dictionaries
Found in: ACM Transactions on Graphics (TOG)
By Anat Levin, Ioannis Gkioulekas, Shuang Zhao, Todd Zickler, Kavita Bala
Issue Date:November 2013
pp. 1-13
Translucent materials are ubiquitous, and simulating their appearance requires accurate physical parameters. However, physically-accurate parameters for scattering materials are difficult to acquire. We introduce an optimization framework for measuring bul...
Understanding the role of phase function in translucent appearance
Found in: ACM Transactions on Graphics (TOG)
By Bei Xiao, Edward H. Adelson, Ioannis Gkioulekas, Kavita Bala, Shuang Zhao, Todd Zickler
Issue Date:September 2013
pp. 1-19
Multiple scattering contributes critically to the characteristic translucent appearance of food, liquids, skin, and crystals; but little is known about how it is perceived by human observers. This article explores the perception of translucency by studying...
