Quickstart

Build the container (only once)

cd into project root directory and run

sudo docker-compose build

This takes a while.

Start the container

cd into project root directory and run

xhost +

followed by

sudo docker-compose up

Open an interactive bash session within running container

Open a new terminal in the project root and type

sudo docker exec -it person_reid bash

This opens a bash prompt within the container.

Setting input videos

To use a new set of input videos copy the video files into the "videos" folder and update the option video_config["cams"] in the file sfmt/config accordingly.

Extracting object detections

To extract objects from a pair of videos in the "videos" folder run the command

python3 detection.py

in the previously opened interactive bash session within the container. For each time step of the videos a pickled file containing the detected objects will be created in the "detections" folder. The naming of the files follows the schema "step_x" indicating the time step of the contained detections.

Using the extracted detections

The reid.py contains a demo of how to use the extracted detections. Run it via

python3 reid.py

in the interactive bash session in the container.
