Hello! I’m Marius Preda

Research. Teaching. Standardisation.

Some work I've done and few people I was working with

Research

Methods and algorithms for 3D graphics representations and compression, augmented reality for entertainment and industry, image processing for 3D reconstruction

Teaching

Image/video/graphics compression, data visualisation, modelling and animation, 3D vision, virtual reality, augmented reality

Standardisation

Convenor of “MPEG coding from 3D graphics and haptics”, 25+ years of experience in international standardisation for multimedia

My main interest

The forward and backward Image pipe-lines

(F) from the physical world to computers – aquisition, understanding, compression, transmission (B) from the computers to the virtual worlds – modelling, compression, synthesis

3D to (processing) (compact) (descriptive) (latent) spaces and back to 3D

Research topics

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation.

3D Graphics Representation and Compression

Efficient 3D graphics representation and compression, advancing both traditional and AI-driven techniques to optimize storage, transmission, and rendering for immersive applications.

Immersive and Interactive Multimedia Systems

Innovative methodologies for immersive and interactive multimedia systems, integrating Human Computer Interfaces, Augmented Reality, and Virtual Reality to enhance user experiences and real-time applications.

AI-Driven Visual Media Processing

Exploring the integration of AI techniques in visual media processing, leveraging deep learning and neural representations to enhance analysis, generation, and interaction with 3D and immersive content.

Virtual Humans and Digital Avatars

Researching the modeling, animation, and interoperability of virtual humans and avatars, integrating AI-driven techniques to enhance realism, interaction, and cross-platform adaptability in immersive environments.

Standardisation

MPEG

I started standardisation activities in 1998 with the first topic being Virtual Humans. Since then, I developped standards for 3D graphics compression, virtual worlds, sensors and actuators, augmented reality

MPEG-4

The first truly multimedia compression standard

MPEG-ARAF

A standard for representing full augmented reality experiences

MPEG-V

A pioneering standard for exchanging assets in virtual worlds and interact with them

MPEG-I

“I” comes from Immersiveness, MPEG-I is a rich set of standards for immersive media

Research projects

A set of national, european and international research projects, financed by public or private instruments
