Research Interests

My current research interests are in the following areas: image processing applications, medical applications, and speech and audio processing for deaf people. The EPSRC funded research project (GR/N25275/01) investigated vision based system for visually impaired and blind people. This is an ongoing project and currently we are investigating how to enhance the existing image processing algorithms for such vision based system. This includes indoor object detection, outdoor scene analysis, and miniaturised vision system. Other research activities currently involve applications in the following areas: image processing techniques to enhance indoor images, diabetic retinopathy related problems, and speech and audio processing applications.

Current and Past Research Projects:

1) Vision Based System as a Secondary Aid for Visually Impaired and Blind People

This is an ongoing project on a vision based portable mobility aid for visually impaired and blind people. The aim of the research is to assist in guiding visually impaired and blind people by identifying objects and landmarks as they walk along their path. The work has established a shape based matching algorithm for object detection from moving image sequences. The work has investigated different methods and algorithms. The work has also looked at other aspects, such as location awareness, indoor navigation and other novel techniques to identify objects commonly found in an indoor environment. A post-doc student conducted part of the above research which was funded by the EPSRC grant (GR/N25275/01). A PhD student has completed his PhD degree on the indoor navigation aspect of this research.

2) A Cooperative Framework for Molecular Biology Database Integration Using Image Object Selection

This research work investigated the ‘database interoperability’ issues and it established a framework for integrating molecular biology databases. The research proposed a component database for gene mutation data and it outlined how to develop a cooperative environment for the molecular biology databases to share information on a common ground. The research also proposed a new concept of image object keying for multi-database query and it developed a matching algorithm using gel electrophoresis image. The research showed how the conventional SQL scripts for multi-database query could be replaced by using image object keying method. This research resulted in a successful PhD completion. .

3) Interoperable Network Security Mechanisms and Proactive Analysis in Communication Network

The research addressed the security issues used in communication network. It specially looked in the following areas: current security technologies with respect to interoperability issues, interoperability between different security elements, and use of proactive strategy.

4) An effective and automated approach to detect abnormalities in retinal images due to diabetic retinopathy

This research has looked at the following issues: effective automated screening, better use of image processing techniques, complexity, and the usability issues. It is anticipated that a new PhD student would continue with this research. The objective is to contribute in developing an automated user-friendly prototype system which will be effective in detecting diabetic retinopathy related problems in a broader context. The research will also look at the hardware issues, such as the possible use of Digital Signal Processor (DSP) and other hardware processors to achieve real-time performance.

5) DSP-based applications

Our current interests are in the following areas: Speech and Audio Processing - automated speech identification from distorted speech, enhancing the quality of sound perceived from conventional hearing aid, fingerprint matching for signature analysis or for other security measures, sign language transmission and detection over smart phone, and facial feature extraction and matching for facial profile recognition.
