In this paper we present a technique that estimates the Structure from Motion (SFM) in a recursive fashion. Traditionally successful SFM algorithms take the set of images and estimate the scene geometry and camera pos...

Proliferative Diabetic Retinopathy (PDR) is characterized by the growth of new abnormal, thin blood vessels called neovascu-larzation that spread along the retinal surface. An automated computer aided diagnosis system...

vision sensors are used to estimate the pose (position and orienta-tion) of mating components in a vision assisted robotic peg-in-hole assembly which is a crucial step in aligning the mating hole-component withthe co...

Official documents consist of text and non-textual elements such as logo, stamp, and signature. Separation of these elements from a scanned document plays a significant role in document image retrieval, recognition, a...

Electrical signals generated in the brain, known as Electroen-cephalographic (EEG) signals, form a non-invasive measure of brain functioning. Baseline states of EEG are Eyes Open (EO) and Eyes Closed (EC) relaxed stat...
