Asia Pacific Seminar on

Applied Topology and Geometry

About APATG

The Asia Pacific Seminar on Applied Topology and Geometry (APATG) is a seminar series covering topological data analysis, persistent homology, computational topology and geometry, random topology and geometry, and their applications. 

The seminar will be held twice a month on Friday as a Zoom meeting starting from 10:30 in Bangalore, India, 14:00 in Kyoto, Japan, and 15:00 in Canberra, Australia as default, but may be changed if necessary. Each talk will be one hour plus Q&A. 

Once you register the necessary information in the Registration page, you will receive the talk information with Zoom link by the day before each seminar. There is no need to register more than once. If you wish to unsubscribe, please send an email to "asia.pacific.atg(at)gmail.com".

#39 Date:  2024/5/10 10:30 (Bangalore), 14:00 (Kyoto), 15:00 (Canberra)

Speaker: Hubert Wagner (University of Florida)

Title: Computing persistent homology of 3D images with billions of voxels using Cubicle

Abstract: Persistent homology is becoming increasingly used in practice. In particular, this is true in the context of (medical) image analysis and computer vision. However, specialized algorithms are necessary to efficiently handle large multidimensional image/voxel/cubical data. I will describe some mathematical and algorithmic techniques I found useful in my 15-year-old collaborative journey towards making such computations efficient. I will also overview available packages, including GUDHI, Cubical Ripser, TTK as well as my software Cubicle.
