Neural Microfacet Fields for Inverse Rendering

no code implementations ICCV 2023 Alexander Mai, Dor Verbin, Falko Kuester, Sara Fridovich-Keil

We present Neural Microfacet Fields, a method for recovering materials, geometry, and environment illumination from images of a scene.

Inverse Rendering Novel View Synthesis

Soft Expectation and Deep Maximization for Image Feature Detection

1 code implementation21 Apr 2021 Alexander Mai, Allen Yang, Dominique E. Meyer

Central to the application of many multi-view geometry algorithms is the extraction of matching points between multiple viewpoints, enabling classical tasks such as camera pose estimation and 3D reconstruction.

Training Deep Neural Networks to Detect Repeatable 2D Features Using Large Amounts of 3D World Capture Data

no code implementations9 Dec 2019 Alexander Mai, Joseph Menke, Allen Yang

We claim that in order to train detectors to work well in indoor environments, they must be robust to this type of geometry, and repeatable under true viewpoint change instead of homographies.

Loop Closure Detection with RGB-D Feature Pyramid Siamese Networks

no code implementations25 Nov 2018 Zhang Qianhao, Alexander Mai, Joseph Menke, Allen Yang

We show for the first time that deep neural networks are capable of detecting loop closures, and we provide a method for generating large-scale datasets for use in evaluating and training loop closure detectors.
