PhD position:

Towards a perceptual metric based on multimodality for video quality  
assessment

The technological progress of the last decade has led to an increased  
network capacity and allowed thus exchanges of larger contents. The  
emergence of HDTV over IP, video exchanges website, distributed video  
surveillance solutions, videoconferencing, video telephony, were the  
consequence of the mentioned progress. This new way of sharing  
information requires the use of rigorous tools to control and ensure  
an acceptable quality in terms for the end-used. From the research  
point of view, an important effort has been devoted to the study of  
tools for assessing video quality of videos and the existing relation  
with the quality of experience (QoE) rather than the quality of  
service (QoS) only. However, current tools cannot address this problem  
completely. We thus find, approaches using a simple weighting of image  
metrics by using the motion. Very few approaches deal with  
multimodality (Video+audio) despite the importance of this aspect for  
QoE.

The proposed PhD program is in the context of multimodal quality  
assessment of a video. This work intends to overcome the shortcomings  
of existing metrics by integrating some useful modules to estimate the  
quality in a similar manner than the end-user judgment. It aims at  
offering an objective solution to quality assessment taking into  
account both temporal and multimodal aspects of a video. Several  
points will be addressed as:

·       Role of motion in video quality estimation

·       Audio-visual saliency effect on quality measurement

·       Multimodal interaction

·       Relationship between compression, bandwidth, motion and quality

·       From QoS to QoE

·       Pooling strategies

·       …

The topic of the PhD can be refocused depending on the project needs  
and the candidate skills.


Funding:

The selected candidate will be an employee of the university of  
Poitiers for 3 years. The gross salary will include health insurance,  
paid leave+public holidays and other benefits. Applications from all  
nationalities are welcomed although some security restrictions may  
apply.


Entry requirement

Applicants should have good background in computer science, artificial  
intelligence, electrical engineering or a related discipline with a  
strong programming ability in a high level language (preferably C/C++,  
Matlab). Candidates should hold at least a Master degree or equivalent  
in Computer Science, Electrical Engineering or a related discipline.


How to apply:

Applicants can make initial enquiries with Dr. Chaker Larabi (chaker.larabi at univ-poitiers.fr 
). If you meet the eligibility criteria and after a selection process  
you’ll be contacted to finalize the application.


Important schedule

The position is open and candidates are expected to send application  
ASAP and before end of March. The PhD thesis can start very soon if  
the candidate fulfills all requirement.
