Dr. Vibhoothi Vibhoothi | ARC Hub for ICT

I am a post-doctoral researcher at Sigmedia Lab. My doctoral thesis, Automated Video Encoder Parameterisation from Streaming to Cinema (TCD, 2025), built the technical foundations for this proposal. The core technology, LiteVPNet, was peer-reviewed and published at IEEE PCS 2025 and presented to the international codec community at the AOMedia Research Workshop and Symposium in 2025. We have disclosed this to Trinity Research and Innovation. I am a contributor to Trinity's work in the Horizon Europe EMERALD project (Grant Agreement 101119800), which addresses sustainable media production and through which TCD joined the Alliance for Open Media.

As Vice-President of VideoLAN (creators of VLC), I work alongside Google, Meta, Netflix, Vimeo, and Apple on the open-source multimedia infrastructure underpinning the video industry. I co-organise VideoLAN Developer Days, the annual gathering of the international codec engineering community, and co-chair two AV2 standardisation activities for the next-generation Alliance for Open Media codec: extended chroma format support and 12-bit depth, both of which directly enable higher picture fidelity for cinematic and post-production workflows. I have actively contributed to open-source AV1 codec development since 2020 (rav1e, dav1d, SVT-AV1).

Research Themes: Sustainability & Environmental Management

Research Programmes

AgriFuTech

An AI genomic prediction engine that learns directly from complex, noisy datasets to deliver reliable trait predictions across crops and environments.

AI-Driven Energy Prediction and Workload Placement

AI-Driven Energy Prediction and Workload Placement

Predicts the energy a computing workload will use before it runs, helping data centres cut costs, reduce emissions and meet EU reporting rules.

AI-Sprayer

A chemical-free precision weeding, fertigation and irrigation platform for organic farms, using computer vision to target hot water at individual weeds.

Climate Parametric Risk Solution (CPRS)

Climate Parametric Risk Solution (CPRS)

Parametric climate risk products for agriculture and renewable energy, helping farmers, lenders and operators manage weather-driven revenue volatility.

ColdChain

A low-cost, disposable RFID tag that signals remotely if frozen goods rise above zero, enabling continuous cold-chain monitoring across the supply chain.

EleVate

An EV fleet battery platform using real-time vehicle data and AI to extend battery life, cut maintenance costs and improve fleet reliability.

IBSO

The Irish Building Stock Observatory links building performance with social, economic and financial data so retrofit investment can be targeted with evidence.

OptiSIFT

Certifies metal powder oxidation at the point of use in additive manufacturing, replacing destructive lab tests that take three to five days.

Physics-Informed Bayesian Network for Predictive Maintenance and Energy Loss Assessment in Thermal Process Plants

Physics-Informed Bayesian Network for Predictive Maintenance and Energy Loss Assessment in Thermal Process Plants

Detects combustion drift, fouling and steam trap failure in SME thermal plants, recovering fuel losses of €14,000–€25,000 a year without costly sensors.

Road AI

Automatically assesses road surface condition from imagery using computer vision, replacing slow manual inspection of defects such as potholes.

TrueFrame

Predicts optimal AV1 encoder settings in a single pass, removing the repeated trial encodes that drive up cloud costs and energy use.

Wingsense

Low-cost Doppler radar sensors that identify and count flying pollinators non-invasively, bringing biodiversity monitoring into environmental IoT networks.
