In this folder we provide the ToF correlation frames of each material at 2 observation distances. The filenames are in the format of:

[material]_d[distance]_f[frequency]_[status].csv

where

- material: "paper", "styrofoam", "towel", or "wax";
- distance: "1" or "2" (all 10 distances will be provided in the future);
- frequency: "80" (all 8 frequencies will be provided in the future);
- status: "orig", without any preprocessing; 
          "fnrm", after fixed pattern noise removal;
          "fnrm_dnrm", after fixed pattern noise removal and depth normalization.

Each .csv file can be viewed in Microsoft Excel, or loaded in MATLAB with "csvread" function. It stores tabular data (separated by commas) consisting 120 rows and 165 columns, which correspond to the correlation frame of 120 pixels in height, and 165 pixels in width.
