Data for EEG Electrode Localization with 3D iPhone Scanning Using Point-Cloud Electrode Selection (PC-ES)

<p>The dataset contains 1) the deidentified, cropped Heges scans collected on 8 subjects (4-7 sub-scans per subject), 2) the merged scans via the PC-ES software from 3 reviewers, and 3) the photogrammetry data (validation data) which also constructed from 3 reviewers. The data is in MATLAB data files (mat-files), which is consistent with the PC-ES software (https://github.com/haley-richards/PC-ES). There are also 2 m-files (MATLAB scripts) that can be used to plot the individual or merged scans.&nbsp;</p><ul><li>cropped_deidentified_scans_pg.mat<ul><li>cropdeidscans a 1 x 8 structure array (8 subjects)</li><li>Each cell contains a structure array of all the sub-scans for the given subject with the following fields:<ul><li>colobj – Matlab point cloud object.
