+## Usage 
+Run [ConAn_RunProcessing.ipynb](ConAn_RunProcessing.ipynb) to extract all frames from video and run processing models. 
+### Body Movement
+For body movement detection we selected [OpenPose](https://github.com/CMU-Perceptual-Computing-Lab/openpose). For our case, we used the 18-keypoint model, 
+which takes the full frame as input and jointly predicts anatomical keypoints and a measurement 
+for the degree of association between them.<br>

 ```
+### Eye Gaze 
+For eye gaze estimation we selected [RT-GENE](https://github.com/Tobias-Fischer/rt_gene). In addition to feeding each video frame to the model, 
+we also input a version of the frame where the left side and the right side are wrapped together. 
+This enables us to detect when a person moves over the edge of the video, as none of the models account for this. 
+As this is a single frame estimation, we then track all subjects throughout the video using a minimal euclidean distance heuristic. <br>

+Notes: 
+- Before using [process_RTGene.py](process_RTGene.py) you need to run [install_RTGene.py](install_RTGene.py)!
+- [OPTIONAL] You can provide a camera calibration file calib.pkl to improve detections. 
+- You need to provide maximum number of people in the video for the sorting algorithm.

+### Object Tracking
+We assume that you are most likely able to define your own study procedure, 
+therefore we decided to simplify object tracking by employing the visual fiducial system [AprilTag 2](https://github.com/AprilRobotics/apriltag), 
+where the tag positions are extracted with their tailored detector.
+
+Note: For Windows we use [pupil_apriltags](https://github.com/pupil-labs/apriltags).
