Project description:

Visual media content rendered by current digital imaging systems differs in perceived quality depending on the system and its applications. To optimize these imaging systems, understanding and modelling perceived visual quality is essential, e.g. to enhance the multimedia experience of human consumers, to improve the efficiency of surveillance systems for public security, and to provide more reliable visualization of medical information.

To embed perceived quality into real-world applications, research aims at automatically predicting visual quality by means of computational algorithms. Over the last several decades, meaningful progress has been made on detecting various types of visual artifacts in different application domains, and on quantifying the local visibility of the detected artifacts. To predict the overall perceived quality, so far the locally measured artifacts are either simply averaged over the spatial (or temporal) domain or operated with an artificial weighting strategy. This may only superficially mimic the way the human visual system determines perceived quality and, consequently, may limit the reliability of a visual quality assessment algorithm. The aim of this PhD project is to achieve a better understanding of human quality assessment behavioural responses to visual artifacts occurring in both spatial and temporal domains, and to develop a perceptually relevant mapping (computational human behavioural model) of local artifact visibility to overall quality perception.

 

Requirements:

The ideal candidate should have a 1st or strong 2.1 honours degree or Masters degree in Computer Science, Electrical Engineering, Physics, Mathematics or a related discipline. Enthusiasm for scientific research and excellent communication skills are essential, as are programming skills (Matlab and/or C++). Prior experience in computer vision, image processing, visual perception or machine learning would be advantageous.

 

Further information:

This full-time UK/EU PhD Scholarship will include fees at the 'home/EU' student rate and maintenance (£13,590 in 2013/14, subject to final confirmation) for three years, depending on satisfactory progress. (Full-time International Fee PhD Studentships will include full fees at the International student rate for three years, dependant on satisfactory progress.)
