Research Intersest

Most of the research topics I am currently working on are in Medical Image Analysis field. The applications are ranging from detecting abnormalites such as exudates or ROP in fundus images using several techniques, from a simple morphology, Scale Space theory to Machine learning approaches.

Currently we are closely working with Dr Sarah Barman at Faculty of Computing, Information Systems and Mathematics, Kingston University London, UK. and Dr. Matthew Dailey at Computer Science and Information Management, School of Engineering and Technology, Asian Institute of Technology.

Many PhD or Master scholarships are now available. Students with thier own scholarships with similar research interest can send your application directly to me. Scholarships will be announced at this URL if available http://www.vcharkarn.com/scholarship/view/122.
