PlaneSDF-based Change Detection for Long-term Dense Mapping
Given point clouds of the source and target scenes, we propose a three-step PlaneSDF-based change detection approach: (1) PlaneSDF volumes are instantiated within each scene and registered across scenes using plane poses; 2D height maps and object maps are extracted per volume via height projection and connected component analysis.
Hybrid Scene Compression for Visual Localization
Besides outperforming previous compression techniques in terms of pose accuracy under the same memory constraints, our compression scheme itself is also more efficient.
Hybrid Camera Pose Estimation
A number of these new hybrid minimal solvers are also presented in this paper.
Toroidal Constraints for Two-Point Localization Under High Outlier Ratios
Adding the knowledge of direction of triangulation, we are able to approximate the position of the camera from two matches alone.
Two forms of minimality in ASPIC+
Many systems of structured argumentation explicitly require that the facts and rules that make up the argument for a conclusion be the minimal set required to derive the conclusion.
Merging the Unmatchable: Stitching Visually Disconnected SfM Models
An important variant of this problem is the case in which individual sides of a building can be reconstructed but not joined due to the missing visual overlap.
The Likelihood-Ratio Test and Efficient Robust Estimation
Robust estimation of model parameters in the presence of outliers is a key problem in computer vision.
Efficient Structured Parsing of Facades Using Dynamic Programming
We propose a sequential optimization technique for segmenting a rectified image of a facade into semantic categories.
Joint 3D Scene Reconstruction and Class Segmentation
Image segmentations provide geometric cues about which surface orientations are more likely to appear at a certain location in space whereas a dense 3D reconstruction yields a suitable regularization for the segmentation problem by lifting the labeling from 2D images to 3D space.
