To recognize three-dimensional objects bounded by smooth curved surfaces from monocular image contours, viewpoint-dependent image features must be related to object geometry. Contour bitangents and innections along with associated parallel tangents points are the projection of surface points that lie on the occluding contour for a ve-parameter family of(More)
We represent arbitrary smooth curved 3D shapes by a discrete set of HOT curves where a surface admits High Order Tangents. These curves determine the structure of the image contours and its catastrophic changes, and there is a natural correspondence between some of them and monocular contour features such as in-ections and bitangents. We present a method(More)
The silhouette of a smooth 3D object observed by a moving camera changes over time. Past work has shown how surface geometry can be recovered using the deformation of the silhouette when the camera motion is known. This paper addresses the problem of estimating both the full Euclidean surface structure and the camera motion from a dense set of silhouettes(More)
A b s t r a c t. This paper presents viewpoint-dependent constraints that relate image features such as t-junctions and inflections to the pose of curved 3D objects. These constraints can be used to recognize and locate object instances in the imperfect line-drawing obtained by edge detection from a single image. For objects modelled by implicit algebraic(More)
In this paper we investigate how to perform face recognition on the hardest experiment (Exp4) in Face Recognition Grand Challenge(FRGC) phase-II data which deals with subjects captured under uncontrolled conditions such as harsh overhead illumination, some pose variations and facial expressions in both indoor and outdoor environments. Other variations(More)
This paper is aimed at developing an Online Intranet College Management System (CMS) that is of importance to either an educational institution or a college. The system (CMS) is an Intranet based application that can be accessed throughout the institution or a specified department. This system may be used for monitoring attendence for the college.

This paper deals with Web Structure Mining, using the Breadth First Search strategy. While browsing the web, the user has to go through many pages of the Internet, filter data and download required information. This task of searching and downloading is time consuming. Sometimes the search queries call for specific option, say, limiting search to few links.(More)
