Why Google Created a Mothership to Oversee Itself

NEWS ANALYSIS: Google was simply too big to be just plain Google. It had to create a new business entity to keep everything in order for investors. Read more »

IBM Moves Tractor Supply Company to the Cloud

IBM announced deals with major retailers, including Tractor Supply Company, to move key operations to the cloud and mobilize employees. Read more »

A one-dimensional homologically persistent skeleton of an unstructured point cloud in any metric space

Real data are often given as a noisy unstructured point cloud, which is hard to visualize. The important problem is to represent topological structures hidden in a cloud by using skeletons with... Read more »

Quaternion Julia Set Shape Optimization

We present the first 3D algorithm capable of answering the question: what would a Mandelbrot-like set in the shape of a bunny look like? More concretely, can we find an iterated quaternion... Read more »

Fast and Exact (Poisson) Solvers on Symmetric Geometries

In computer graphics, numerous geometry processing applications reduce to the solution of a Poisson equation. When considering geometries with symmetry, a natural question to consider is whether and how the symmetry can... Read more »

Stable Topological Signatures for Points on 3D Shapes

Comparing points on 3D shapes is among the fundamental operations in shape analysis. To facilitate this task, a great number of local point signatures or descriptors have been proposed in the past... Read more »

Learning class-specific descriptors for deformable shapes using localized spectral convolutional networks

In this paper, we propose a generalization of convolutional neural networks (CNN) to non-Euclidean domains for the analysis of deformable shapes. Our construction is based on localized frequency analysis (a generalization of... Read more »

Unconditionally Stable Shock Filters for Image and Geometry Processing

This work revisits the Shock Filters of Osher and Rudin [OR90] and shows how the proposed filtering process can be interpreted as the advection of image values along flow-lines. Using this interpretation,... Read more »

Can bi-cubic surfaces be class A?

'Class A surface’ is a term in the automotive design industry, describing spline surfaces with aesthetic, non-oscillating highlight lines. Tensor-product B-splines of degree bi-3 (bicubic) are routinely used to generate smooth design... Read more »
