The Geometry of Nodal Sets and Outlier Detection

This repository contains a Matlab implementation of

for outlier detection, described in the paper: Xiuyuan C., Mishne G. and Steinerberger S. (2017). The Geometry of Nodal Sets and Outlier Detection. arXiv preprint arXiv:1706.01362. Included are an implementation of outlier detection on a 3D mesh (Stanford bunny from http://graphics.stanford.edu/data/3Dscanrep) and outlier detection on an image.
