Processed Data for ConfLab: A Data Collection Concept, Dataset, and Benchmark for Machine Analysis of Free-Standing Social Interactions in the Wild

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