A Theory of Shape Reconstruction from Heat Conduction and Shading
Akihiko Oharazawa, Sriram Narayanan, Mani Ramanagopal +1
Shape from shading using a single image of a Lam- bertian surface is inherently ambiguous. When the light source direction is known, the surface normal estimation has a cone- ambig…
Dual Band Thermal Videography: Separating Time-Varying Reflection and Emission Near Ambient Conditions
Sriram Narayanan, Mani Ramanagopal, Srinivasa G. Narasimhan
Long-wave infrared radiation captured by a thermal camera includes (a) emission from an object governed by its temperature and emissivity, and (b) reflected radiation from the surr…
VT-Intrinsic: Physics-Based Decomposition of Reflectance and Shading using a Single Visible-Thermal Image Pair
Zeqing Yuan, Mani Ramanagopal, Aswin C. Sankaranarayanan +1
Decomposing a scene into its reflectance and shading is a challenge due to the lack of extensive ground-truth data for real-world scenes. We introduce a novel physics-based approac…
Digital Kitchen Remodeling: Editing and Relighting Intricate Indoor Scenes from a Single Panorama
Guanzhou Ji, Azadeh O. Sawyer, Srinivasa G. Narasimhan
We present a novel virtual staging application for kitchen remodeling from a single panorama. To ensure the realism of the virtual rendered scene, we capture real-world High Dynami…
Indoor Heat Estimation from a Single Visible-Light Panorama
Guanzhou Ji, Sriram Narayanan, Azadeh Sawyer +1
This paper introduces a novel image-based rendering technique for jointly estimating indoor lighting and thermal conditions from paired indoor-outdoor high dynamic range (HDR) pano…
