SPICE: Simple and Practical Image Clarification and Enhancement
Alexander Belyaev, Pierre-Alain Fayolle, Michael Cohen
We introduce a simple and efficient method to enhance and clarify images. More specifically, we deal with low light image enhancement and clarification of hazy imagery (hazy/foggy…
PyFRep: Shape Modeling with Differentiable Function Representation
Pierre-Alain Fayolle, Evgenii Maltsev
We propose a framework for performing differentiable geometric modeling based on the Function Representation (FRep). The framework is built on top of modern libraries for performin…
Accuracy Improvements for Convolutional and Differential Distance Function Approximations
Alexander Belyaev, Pierre-Alain Fayolle
Given a bounded domain, we deal with the problem of estimating the distance function from the internal points of the domain to the boundary of the domain. Convolutional and differe…
A Survey of Methods for Converting Unstructured Data to CSG Models
Pierre-Alain Fayolle, Markus Friedrich
The goal of this document is to survey existing methods for recovering CSG representations from unstructured data such as 3D point-clouds or polygon meshes. We review and discuss r…
Reconstruction of Convex Polytope Compositions from 3D Point-clouds
Markus Friedrich, Pierre-Alain Fayolle
Reconstructing a composition (union) of convex polytopes that perfectly fits the corresponding input point-cloud is a hard optimization problem with interesting applications in rev…
Signed Distance Function Computation from an Implicit Surface
Pierre-Alain Fayolle
We describe in this short note a technique to convert an implicit surface into a Signed Distance Function (SDF) while exactly preserving the zero level-set of the implicit. The pro…
