Pedagogical Jupyter notebooks for topological data analysis. Topics include basic shapes, sliding window audio/video, lower star filtrations, 3D shapes, spaces of images patches

linmdtw

A linear memory, parallelizable algorithm for Dynamic Time Warping (DTW). Also contains cython implementations of FastDTW, and Memory-Restricted Multiscale DTW (MrMsDTW), and globally constrained DTW with the Sakoe-Chiba band (so-called "cdtw")

Jupyter Notebook

GraphDitty

Similarity network fusion of features for clean self-similarity matrices in audio, as well as Javascript tools to play SSMs and spring graphs synchronized to audio

PoissonImageEditing

A standalone poisson image editing implementation in Java. Used to blend together images seamlessly

pyhks

Simple dependency free Python library for the Heat Kernel Signature on triangle meshes

GeometricCoverSongs

Geometry features for block window cover song identification (a continuation of my ISMIR 2015 paper)

LetItBee

A Python Implementation of Driedger's "Let It Bee" Technique for Audio Mosaicing

FaceJam

Math412S2017
