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…
PhyCo: Learning Controllable Physical Priors for Generative Motion
Sriram Narayanan, Ziyu Jiang, Srinivasa Narasimhan +1
Modern video diffusion models excel at appearance synthesis but still struggle with physical consistency: objects drift, collisions lack realistic rebound, and material responses s…
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…
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…
