Recording setup
Camera view, subject and arena layout: a tank seen from the side, from above or a multiwell plate.
Video analysis for behavioural research
Stoodia Vision
Turn experiment recordings and live camera streams into trajectories you can check, metrics you can trace and group comparisons ready for a report. The research task is defined by a plug-in scenario.
- Videos stay on your computer
- Scenario version is recorded
- Every trajectory can be reviewed
Scenarios as plug-ins
One application, a scenario for each experiment
Stoodia Vision provides the project, video, review and statistics. A scenario adds the science for a specific type of recording.
Tracker and detector
Each scenario brings a tracking engine and a model trained for its kind of footage.
Metrics
The measurements that make sense for this setup, with quality-control indicators.
Reports and export
Visualizations, report layouts and export formats with the method and data provenance.
Scenarios are installed from the catalogue as signed packages. Each one has its own version and is updated without reinstalling the application.
How it works
The whole experiment in one project
- 1
Set up the experiment
Groups, conditions, arenas, analysis zones and physical scale.
- 2
Add video
Import recordings or record from one or several cameras.
- 3
Track
Works on CPU. An NVIDIA GPU with CUDA is recommended for fast tracking.
- 4
Review trajectories
Check gaps and false detections against the video, fix intervals, record the quality decision.
- 5
Analyse behaviour
Movement and spatial metrics, events, states and transitions over chosen time intervals.
- 6
Compare and export
Distributions, confidence intervals, effect sizes and statistical tests, exported with the calculation parameters.
Available scenarios
Choose the scenario that matches your recording
Install only what your experiment needs. Recordings are compared only within the same scenario.
Fish
Adult fish, side view
One adult fish per arena, filmed through the side wall of a tank.
Measures
- distance travelled
- mean speed
- time in the top and bottom zones
Adult fish, top view
One adult fish per arena, filmed from above.
Measures
- distance travelled
- mean speed
- time in the centre zone
Adult shoal in 3D, two synchronized cameras
The same fish are filmed simultaneously from the side and above. The scenario reconstructs individual trajectories in calibrated 3D space and reports identity ambiguity and stereo coverage for review.
Measures
- 3D path and speed
- nearest-neighbour distance
- polarization and alignment
- shoal spread and volume
- vertical and depth distribution
- proximity bouts
- individual kinematics
- identity and stereo quality
Synthetic recording, real scenario output
Fish larvae in a multiwell plate
Head, body contour, centre and tail of one larva in every well. 24- and 96-well templates and custom grids.
Measures
- distance per well
- mean speed
- path straightness
- plate summary

Limits of use
Each scenario is validated only for its own recording conditions, and the application shows its status when you choose it. “Adult fish, side view” is ready for work; the other Fish scenarios are previews.
New recording conditions, other species and experiments in which animals occlude one another need visual review of trajectories and a hand-annotated validation sample of your own. Stoodia Vision provides the tools for that review but does not replace the researcher’s scientific judgement.
