Abstract: We propose a convolutional neural network which generates high-quality ray-traced material visualizations on a shaderball, to aid material synthesis and editing.

Speaker(s) Bio: Aakash KT, International Institute of Information Technology, Hyderabad, India
I am currently a MS by research student at Computer Vision Lab (CVIT), which is where I completed my BTech in Computer Science Engineering. My research advisor is Dr. PJ Narayanan. My research involves playing around with the light transport equation, in combination with machine learning (in other words, I work on Computer Vision/Computer Graphics).

Parikshit Sakurikar, International Institute of Information Technology, Hyderabad; DreamVu Inc., India
I am currently a Ph.D. candidate at the Center for Visual Information Technology at IIIT-Hyderabad. I work with Prof. P. J. Narayanan on topics related to Computational Photography and Machine Learning. My main area of research is Epsilon Focus Photography, which deals with capturing and processing multi-focus images, depth from focus, measurement of focus/defocus-blur and post-capture control of depth-of-field. I am also broadly interested in Computer Vision, Computer Graphics and High Performance Computing.

Saurabh Saini, International Institute of Information Technology, Hyderabad, India
I am a Ph.D. student under the guidance of Prof. P. J. Narayanan in Center for Visual Information Technology (CVIT) lab, a part of Kohli Center on Intelligent Systems (KCIS), at the International Institute of Information Technology-Hyderabad (IIIT-H) India. My general research interest is in the topics related to Computer Vision, Machine Learning and Optimization, especially applied to 2D or 3D reconstruction. Currently I am working on Inverse Rendering and Inverse Light Transport problems. Specifically, I am focusing on Intrinsic Image Decomposition (separating object property based vs. light related components in an image).
