%X <p>This folder contains processed data (video and wearable sensors) for 16 mins<br>
of interaction that were annotated for the Conflab dataset.<br>
<br>
<strong>./cameras</strong><br>
   ./video_segments contains the overhead video recordings for 5 cameras<br>
   in MP4 files. These are split into 2 min segments, down-scaled to 960x540px,<br>
   and denoised. The resulting files are the ones that were used to annotate poses<br>
   and actions.<br>
<br>
   For applications that require higher resolutions, the original video files in the<br>
   "data_raw" folder are at 1920x1080 resolution and a script is provided to extract<br>
   the same 2min segments.<br>
<br>
   ./camera-calibration contains the camera instrinsic files obtained from:<br>
   https://github.com/idiap/multicamera-calibration. Camera extrinsic parameters<br>
   can be calculated using the existing intrinsic parameters and the instructions<br>
   in the multicamera-calibration repo. The coordinates in the image are provided<br>
   by the crosses marked on the floor, which are visible in the video recordings.<br>
   The crosses are 1m apart (=100cm).  <br>
<br>
<strong>./wearables</strong><br>
   contains one single dataframe with aggregated sensor information<br>
   (accelerometer, gyroscope, magnetometer, rotation, proximity) per each person.<br>
   The data has been interpolated and imputed at 50Hz (fixed). The code used to obtain<br>
   these files from the raw data can be found at:<br>
   https://github.com/TUDelft-SPC-Lab/conflab/blob/master/preprocessing/midge/preprocess.ipynb<br>
<br>
   This code can be used to preprocess larger segments of the werable data<br>
   from the "data_raw" folder.<br>
<br>
   Audio files are not part of this folder, but are provided in the "data_raw" file.</p>
