Irene Viola



I am a senior (tenured) researcher at Centrum Wiskunde & Informatica. My interests lie in multimedia compression, transmission, and quality evaluation. My research is currently focused on Quality of Experience (QoE) metrics and methodologies for immersive multimedia systems (i.e., volumetric video for XR applications). 

A recorded talk about my research, given for the 75th anniversary of CWI, is available here.

INDUX-R (Horizon Europe)


INDUX-R envisions a human-centric XR ecosystem that will transform European industrial sectors by empowering humans and creating innovative XR products and services of significant added value. It targets concrete scientific breakthroughs integrated into technological enablers that will be applied in use cases driven by real-life needs while having the potential to be replicated in several other applications. These breakthroughs are focused on core XR technologies, namely, digitization and creation of XR assets, realistic animation, light-field HMDs, XR media streaming, and egocentric perception. To address the challenges that multi-user XR applications pose, INDUX-R will implement a highly scalable, zero-touch 5G architecture and a secure, interoperable IoT network that can accommodate fluctuating demands and minimize waste of resources.

TransMIXR (Horizon Europe)

The mission of TransMIXR is to introduce leading-edge technologies and experiences built around public values: to inform & entertain, to connect & inspire, to educate and empower. Its ambition is to strengthen the democratic mission and competitiveness of the European Cultural and Creative Sector with intelligent AI and XR technologies that are user-centric, transparent, trustworthy, inclusive, and accountable.

VOXReality (Horizon Europe)

VOXReality is an ambitious project whose goal will be to facilitate and exploit the convergence of two important technologies, natural language processing (NLP) and computer vision (CV). Vision systems drive both AR and VR, while language understanding adds a natural way for humans to interact with the backends of XR systems, or create multi-modal XR experiences combining vision and sound. 

September 2021 - present


The project focuses on on designing and integrating novel algorithms to improve compression and transmission efficiency of immersive media contents through Quality of Experience (QoE) optimization.
