Research Interests
Digital Image Processing (especially, Medical Image Processing)

Feature detection and image segmentation are the primary areas of my research interests. Analysis of 3-D maxillofacial image data is the title of my doctoral dissertation, which focused on the analysis of the human dentition and jawbone for orthodontic treatment and surgery. The extraction of anatomical features in retinal images is one of my recent research topics.

Computer Vision and Remote Sensing

Depth estimation and motion analysis are the areas of my long-term research interests. Depth estimation is the central issue in dealing with stereo (or more) images, while motion analysis is concerned with the process of time-sequential images. I am particularly interested in the correspondence problem that has to be solved for estimating both depth and motion.

Object Classification and Recognition

Image understanding is another area of my interests. This category has various applications for biometrics and industry, such as security control, parts inspection, grading and sorting, etc. A popular research topic in biometrics is human face recognition which I have worked on.
