Fast Tractography Streamline Search

Title

Fast Tractography Streamline Search.

• Hierarchical search using a space partitioning tree (binary search tree / KD-tree ).
• Using an adapted distance measure (Entry-wise matrix distance).

Project Description

Create a repository for a Fast tractography / streamline search method. And develop useful scripts / methods.

Link to project repository/sources

https://github.com/StongeEtienne/tractography-search

Goals for Brainhack Global

• Find an optimized space partitionning tree that can be adapted (Nanoflann).
• Adapt distances adapted for tractography streamlines (L21 entry-wise).
• Create, adapt and optimize the search function, (C++, with python “binder”).
• Discuss & choose a Library architecture / structure.
• Create usefull scripts to search streamlines within a tractogram.
• Clustering algorithms using a sparse distance matrix.

Good first issues

1. issue one: Discuss about the project (how can you help with this project or learn about tractography).
2. issue two: Code or improve functions to search for similar streamlines.
3. issue three: Create scripts and utlity functions.

Skills

• Python : Any level (want to learn python for diffusion / tractography ?)
• Python : Intermediate (want to do streamline clustering ?)
• C++ : Intermediate (want to improve / optimize “core” functions)
