The Koster Seafloor Observatory is an open-source, citizen science and machine learning approach to analyse subsea movies.
The system processes underwater footage and its associatead metadata into biologically-meaningfull information. The format of the underwater media is standard (.mp4 or .png) and the associated metadata should be captured in three csv files (“movies”, “sites” and “species”) following the Darwin Core standards (DwC).
This data management module contains scripts and resources to move and process underwater footage and its associated data (e.g. location, date, sampling device).
The system is built around a series of easy-to-use Jupyter notebook tutorials. Each tutorial allows users to perform a specific task of the system (e.g. upload footage to the citizen science platform or analyse the classified data). The notebooks rely on the koster utility functions.
| Name | Description | Try it! |
|---|---|---|
| 1. Check footage and metadata | Check format and contents of footage and sites, media and species csv files |   |
| 2. Upload new media to the system* | Upload new underwater media to the cloud/server and update the csv files | |
| 3. Upload clips to Zooniverse | Prepare original footage and upload short clips to Zooniverse | |
| 4. Upload frames to Zooniverse | Extract frames of interest from original footage and upload them to Zooniverse | |
| 5. Train ML models | Prepare the training and test data, set model parameters and train models | |
| 6. Evaluate ML models | Use ecologically-relevant metrics to test the models | |
| 7. Publish ML models | Publish the model to a public repository | |
| 8. Analyse Zooniverse classifications | Pull up-to-date classifications from Zooniverse and report summary stats/graphs | |
| 9. Download and format Zooniverse classifications | Pull up-to-date classifications from Zooniverse and format them for further analysis | Coming soon |
| 10. Run ML models on footage | Automatically classify new footage | Coming soon |
* Project-specific tutorial
If you want to fully use our system (Binder has computing limitations), you will need to download this repository on your local computer or server.
Clone this repository using
git clone --recurse-submodules https://github.com/ocean-data-factory-sweden/kso-data-management.gitNavigate to the folder where you have cloned the repository or unzipped the manually downloaded repository.
cd kso-data-managementThen install the requirements by running.
pip install -r requirements.txtIf you will work in a new project you will need to input the information about the underwater footage files, sites and species of interest. You can use a template of the csv files and move the directory to the "db_starter" folder.
You will need files of underwater footage to run this system. You can download some samples and move them to db_starter. You can also store your own files and specify their directory in the tutorials.
Before using Option 2, users should have login credentials and have setup the Chalmers VPN on their local computers

To use the Jupyter Notebooks within the Alvis HPC cluster, please visit Alvis Portal and login using your SNIC credentials.
Once you have been authorized, click on "Interactive Apps" and then "Jupyter". This open the server creation options.
Here you can keep the settings as default, apart from the "Number of hours" which you can set to the desired limit. Then choose either Data Management (Runtime (User specified jupyter1.sh)) or Machine Learning (Runtime (User specified jupyter2.sh)) from the Runtime dropdown options.
This will directly queue a server session using the correct container image, first showing a blue window and then you should see a green window when the session has been successfully started and the button "Connect to Jupyter" appears on the screen. Click this to launch into the Jupyter notebook environment.
Important note: The remaining time for the server is shown in green window as well. If you have finished using the notebook server before the alloted time runs out, please select "Delete" so that the resources can be released for use by others within the project.

- Installing conda
- Create new environment (e.g. "new environment")
- Install git and pip (with conda)
- Clone kso repo
- pip install ipykernel
- python -m ipykernel install --user --name="new_environment"
- from the jupyter notebook select kernel/change kernel
Before pushing your code to the repo, please run black on the code you have edited. You can install black package using pip:
pip install blackIf you experience issues uploading movies to Zooniverse, it might be related to the libmagic package. In Windows, the following commands seem to work:
pip install python-libmagic
pip install python-magic-bin
