Object-oriented persistent homology
Persistent homology provides a new approach for the topological simplification of big data via measuring the life time of intrinsic topological features in a filtration process and has found its success in scientific and engineering applications. However, such a success is essentially limited to qualitative data classification and analysis. Indeed, persistent homology has rarely been employed f...

Persistent homology provides a new approach for the topological simplification of big data via measuring the life time of intrinsic topological features in a filtration process and has found its success in scientific and engineering applications. However, such a success is essentially limited to qualitative data characterization, identification and analysis (CIA). Indeed, persistent homology ha...
متن کاملConceptualization of Object Compositions Using Persistent Homology
A topological shape analysis is proposed and utilized to learn concepts that reflect shape commonalities. Our approach is two-fold: i) a spatial topology analysis of point cloud segment constellations within objects. Therein constellations are decomposed and described in an hierarchical manner – from single segments to segment groups until a single group reflects an entire object. ii) a topolog...
متن کاملDolphin : Persistent , Object - Oriented and Networked
This thesis addresses the problems associated with the design of a new generation of high-performance computer systems for use with object-oriented languages. The major contribution is a novel design for the utilization of object addressing and multiple stacks within RISC-style processors, and a proposal for object-addressed stable electronic memory capable of supporting much higher performance...
متن کاملGait-Based Carried Object Detection Using Persistent Homology
There are surveillance scenarios where it is important to emit an alarm when a person carrying an object is detected. In order to detect when a person is carrying an object, we build models of naturally-walking and object-carrying persons using topological features. First, a stack of human silhouettes, extracted by background subtraction and thresholding, are glued through their gravity centers...
