Flexible Techniques for Differentiable Rendering with 3D Gaussians
Leonid Keselman, Martial Hebert
Fast, reliable shape reconstruction is an essential ingredient in many computer vision applications. Neural Radiance Fields demonstrated that photorealistic novel view synthesis is…
Approximate Differentiable Rendering with Algebraic Surfaces
Leonid Keselman, Martial Hebert
Differentiable renderers provide a direct mathematical link between an object's 3D representation and images of that object. In this work, we develop an approximate differentiable…
Direct Fitting of Gaussian Mixture Models
Leonid Keselman, Martial Hebert
When fitting Gaussian Mixture Models to 3D geometry, the model is typically fit to point clouds, even when the shapes were obtained as 3D meshes. Here we present a formulation for…
Dynamics Based 3D Skeletal Hand Tracking
Stan Melax, Leonid Keselman, Sterling Orsten
Tracking the full skeletal pose of the hands and fingers is a challenging problem that has a plethora of applications for user interaction. Existing techniques either require weara…
Intel RealSense Stereoscopic Depth Cameras
Leonid Keselman, John Iselin Woodfill, Anders Grunnet-Jepsen +1
We present a comprehensive overview of the stereoscopic Intel RealSense RGBD imaging systems. We discuss these systems' mode-of-operation, functional behavior and include models of…
