3-D Material Style Transfer for Reconstructing Unknown Appearance in Complex Natural Materials
Shashank Ranjan, Corey Toler-Franklin
We propose a 3-D material style transfer framework for reconstructing invisible (or faded) appearance properties in complex natural materials. Our algorithm addresses the technical…

Non-Photorealistic Rendering of Layered Materials: A Multispectral Approach
Corey Toler-Franklin, Shashank Ranjan
We present multispectral rendering techniques for visualizing layered materials found in biological specimens. We are the first to use acquired data from the near-infrared and ultr…

Tight Performance Bounds for Compressed Sensing With Conventional and Group Sparsity
Shashank Ranjan, Mathukumalli Vidyasagar
In this paper, we study the problem of recovering a group sparse vector from a small number of linear measurements. In the past the common approach has been to use various "group s…
