Past Projects [Current Projects]
		A Computational Model for Repeated Pattern Perception using Crystallographic Groups This project is developing a computational model for repeated pattern perception that is able to automatically classify a given pattern into one of the 7 frieze groups, one of the 17 wallpaper groups, or one of the 230 space groups.
		A Statistical Quantification of Human Brain Asymmetry Constructing image index features to retrieve medically similar cases from a multimedia medical database.
		Evaluation of MSP Extraction Algorithms The aim of this project is to evaluate different state-of-art algorithms for automatic extraction of the mid-sagital plane in brain images.
		Face Recognition Recognizing people from images and videos.
		Facial Asymmetry as a Biometric We are investigating the effect of facial asymmetry measurement statistics as a biometric under expression variations.
		Image De-fencing We introduce a novel image segmentation algorithm that uses translation symmetry as the primary foreground/ background separation cue.
		Near Regular Texture -- Analysis, Synthesis and Manipulation We are developing near regular texture synthesis algorithms for improved natural appearances.
		Predicting Risk of Alzheimer's Disease From Shape Features The goal of this project is to use computer vision techniques to help predict risk of Alzheimer's Disease in elderly patients.
		Texture Replacement in Real Images We are developing methods to replace some specified texture patterns in an image while preserving lighting effects, shadows and occlusions.
