PUGeo-Net: A Geometry-centric Network for 3D Point Cloud Upsampling
European Conference on Computer Vision, 2020This paper addresses the problem of generating uniform dense point clouds to describe the underlying geometric structures from given sparse point clouds.

Finite Galois arithmetics are well-known; finite geometries however, though more interesting to the amateur, have not really acquired professional status and do not appear to any great extent in standard works. The following example arose from a chance remark in Mathematics for T. C. Mits, by L. R. and H. G.

The following paragraphs have been assembled in consequence of my reading Dr. Cundy’s note on 25-point geometry. Towards the end of it, apparently mindful of the adjunction of a “ line at infinity ” to the Euclidean plane, he adjoins a line to the 25-point plane and so obtains a geometry of 31 points. Here I reverse this procedure : I start with the 31-

Axiomatizability of Geometry without Points
Synthese, 1960The aim of this paper is to make more precise the well-known conviction that geometry may be built without speaking about points. In the first section we prepare some general syntactical theorems which are needed. In the second section we apply these theorems to a certain theory of topology without points.

3D Point Cloud Attribute Compression Using Geometry-Guided Sparse Representation
IEEE Transactions on Image Processing, 20203D point clouds associated with attributes are considered as a promising paradigm for immersive communication. However, the corresponding compression schemes for this media are still in the infant stage.

Geometry Coding for Dynamic Voxelized Point Clouds Using Octrees and Multiple Contexts
IEEE Transactions on Image Processing, 2020We present a method to compress geometry information of point clouds that explores redundancies across consecutive frames of a sequence. It uses octrees and works by progressively increasing the resolution of the octree.

Mahalanobis Based Point to Distribution Metric for Point Cloud Geometry Quality Evaluation
IEEE Signal Processing Letters, 2020Nowadays, point clouds (PCs) are a promising representation format for immersive content and target several emerging applications, notably in virtual and augmented reality. However, efficient coding solutions are critically needed due to the large amount

Computer Vision and Pattern Recognition
We present MoGe, a powerful model for recovering 3D geometry from monocular open-domain images. Given a single image, our model directly predicts a 3D point map of the captured scene with an affine-invariant representation, which is agnostic to true ...
