This Readme file was created for a basic overview of how to use the gp_cochlea_estimate.m file to estimate the pose of a guinea pig cochlea. It outlines the folder structure and files necessary to run the code as well as a snippet of example code to test the program.

This code is based off of a paper to be published in Otology and Neurogology. Link will be provided soon.

This method is based off of the JRMPC algorithm and paper found [here].(https://team.inria.fr/perception/research/jrmpc/)

You can also check out a basic Qt gui created that can be used to record point touching and will output the required file in another repo I made here. More details are included specifying how/where to select points. NOTE: It uses an NDI Polaris motion tracking device. You'll need to include whichever motion tracking device you're using.

TO RUN: To run the code, load the the 6x3 array of feature points file you will use (see sample_data_file.dat) into the gp_cochlea_estimate. The 6 features needed to be touched and recorded by a motion tracking system are (please see the attached paper for reference):

CL, MN, OS, RWA, RWP, and LLI

Then run code as seen in sample_run.m.
