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

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. 

• cropped_deidentified_scans_pg.mat
  • cropdeidscans a 1 x 8 structure array (8 subjects)
  • Each cell contains a structure array of all the sub-scans for the given subject with the following fields:
    • colobj – Matlab point cloud object. This is the Heges output cropped and deidentitied.
    • tri – triangulation related to the nodes (Location) of the colobj object
• merged_scans – output from the PCES software that merged the subscans from Heges
  • outputres a 3 x 8 structure array (3 reviewers/readers of scans and 8 subjects)
  • Each cell contains a structure array scans with the following fields:
    • colobj – the merged scans, albeit separated by angular sectors
    • tdat_mrg – merged electrodes
    • tdat_full – full-set of electrodes
    • tri_mrg - triangulation related to the nodes (Location) of the colobj object
• photogram_dat – photogrammetry-base electrodes 3 x 8 structure array (3 reviewers/readers of scans and 8 subjects)
