Judith Redi

Dr. Judith Redi

Judith Redi obtained the MSc in Electronic Engineering in 2006 from Genoa University, Italy. In 2007 she joined the Smart Embedded Application Laboratory (SEALab) of the Genoa University as a PhD student in Space Sciences and Engineering. Her PhD project was entirely funded by Philips Research and focused on the study and modeling of visual quality perception mechanisms. She also was a guest researcher at Philips Research Labs, Eindhoven, the Netherlands, in 2007 and of the Man-Machine Interaction group of Delft University of Technology in 2009.

In 2010 her PhD thesis “Visual Overall Quality Assessment: a perception-driven framework based on Computational Intelligence techniques” received the “best engineering thesis award” from the University of Genoa. In 2010 she was appointed as a post-doc at Eurecom research institute, where she focused on digital image forensics and 3D face recognition.

She is currently an Assistant Professor in the Man-Machine Interaction group of Delft University of technology, where her main research interests are Visual Perception, Image Quality study and modelling, Intelligent Lighting applications.


Ernestasia Siahaan

M.Sc. Ernestasia Siahaan

Ernestasia Siahaan obtained her M.Sc. in Computer Science and Information Engineering from the National Central University of Taiwan in 2013. Her thesis focused on applying machine learning techniques for environmental sound recognition.

Ernestasia is now working as a PhD researcher in the Multimedia Computing Group of Delft University of Technology. Her research aims to model user Quality of Experience when interacting with multimedia collection. Currently she is looking into factors that influence user judgment of image aesthetic appeal and perceptual quality.


Christina Katsimerou

M.Sc. Christina Katsimerou

Christina obtained her M.Sc. degree in Electrical and Computer Engineering from Aristotle University of Thessaloniki (Greece), in March 2011.

She is currently working as a PhD researcher at the Delft University of Technology, in the Multimedia Computing group, on the topic of automatic emotion and mood recognition from videos. The PhD position is part of the ACE project, funded by Philips Research and TU Delft.

In her current research she uses tools from computer vision, signal processing and machine learning, to model and recognize human non-interactive affective behaviour.

Yi Zhu

M.Sc. Yi Zhu

Yi Zhu received the B.S. degree in telecommunication from the Nanjing University of Posts and Telecommunications, Nanjing, China, in 2009, and the M.Sc. degree in telecommunication from the Southeast University of Nanjing, Nanjing, China, in 2012.

He is currently pursuing the Ph.D. degree in the Multimedia Computing Groupat Delft University of Technology, Delft, the Netherlands. His research interests include measuring and modeling quality of multimedia experience, with a focus on the effects of social context and individual characteristics on viewing experience.



Former Group Members


Prof. Ingrid Heynderickx

Prof. Dr. Ingrid Heynderickx

Ingrid joined Philips Research in 1987, and has been involved in various research areas since then: optimization of the optics of LCDs, characterization of the rheological behavior of liquid crystalline polymers, and the functional evaluation of personal care devices. 

Currently, she is noted for her expertise in the perceptive evaluation of display and lighting systems, a research area in which she bridges technology with human perception and needs. 

She is member of the Society for Information Displays (SID), and was chairman of SID’s Applied Vision subcommittee from 2002 till 2007. In 2008, she became a SID Fellow and chairman of its European Committee. 

In 2005, she was appointed Guest Research Professor at the Southeast University of Nanjing (China) and Part-time Full Professor at the University of Technology in Delft (the Netherlands). 

In 2009 she received the National Friendship Award of China.


Hantao Liu

Dr. Hantao Liu

Dr Hantao Liu received his MSc degree from The University of Edinburgh (United Kingdom) in September 2005, with a Master's thesis on Computer Vision and Signal Processing. In October 2006, he started his PhD at Delft University of Technology (The Netherlands), with a project 'Objective Image Quality Assessment' funded by Philips Research Laboratories Eindhoven.

Hantao is currently an Assistant Professor in the School of Computer Science & Informatics at Cardiff University (United Kingdom).



Hani Alers

ir. Hani Alers

Hani received the MSc degree in Media and Knowledge Engineering from the Delft University of Technology in September 2007, where he currently works as a researcher.

His research interests include modeling human image and video quality perception, as well as employing Internet technology in educational systems.

Sin Lin Wu

ir. Sin Lin Wu

Sin Lin completed her M.Sc. degree in Media and Knowledge Engineering from Delft University of Technology in 2010.

For her graduation project she studied the use of auto-stereoscopic 3D displays in mobile devices, this project was conducted in cooperation with Motorola.

Currently she is conducting research on image quality evaluation of 3D video content. This project is a joint collaboration between Delft University of Technology, Intel and Arizona State University.

This research group is part of the Multimedia Computing Group group based in the Technical University of Delft
