Frequency-based heuristics for material perception.
People often make rapid visual judgments of the properties of surfaces they are going to walk on or touch. How do they do this when the interactions of illumination geometry with 3-D material structure and object shape result in images that inverse optics algorithms cannot resolve without externally imposed constraints? A possibly effective strategy would be to use heuristics based on informati...
متن کاملFrequency based Kernel Estimation for Progressive Photon Mapping Supplementary Material
We present an extension to Hachisuka et al.’s Progressive Photon Mapping (or PPM) algorithm [Hachisuka et al. 2008] in which we estimate the radius of the density estimation kernels using frequency analysis of light transport [Durand et al. 2005]. We predict the local radiance frequency at the surface of objects, and use it to optimize the size of the density estimation kernels, in order to acc...
متن کاملRobotic Perception of Material
In this paper, we develop a conceptual framework in which acts of manipulation are undertaken for the sake of perceiving material. Within this framework, we disambiguate different materials by actively contacting and probing them, and by sensing the resulting forces, displacements, and sounds. We report experimental results from four separate implementations of this framework using a variety of...
متن کاملSupplemental Material for “ New Insights Into Diversification of Hyper - Heuristics ”
In this document, we present the supplemental materials for the paper “New Insights Into Diversification of HyperHeuristics”. More specifically, the document consists of 4 sections. In Section I, we present the complete results of the sensitivity analysis, for the Low Level Heuristic (LLH) parameters. In Section II, the numerical results for both HIP-HOP (recursive acronym of “HIP-HOP is an Ins...
