Comparative Study of Structure-from-Motion Algorithms 3D Shape Reconstruction
Abstract: 3D shape reconstruction from multiview photographs and video sequences (2D images) is an active area of research. Existing face recognition systems are based on 2D facial images and exhibit well-known deficiencies. Accordingly, the face recognition research is gradually shifting from classical 2D to sophisticated 3D or hybrid 2D/3D. Currently the 3D reconstruction algorithms may be grouped in to four categories. These are shape-from-X, 3D morphable model (3DMM), structure from motion …

Automating Acquisition through SOUL 3.0
Abstract: Library automation is an integral part of the development process of any library or resource center. Traditionally this includes automation of acquisition, serialization, cataloging and circulation. But most libraries do list entries of reading material and display them via OPAC. These libraries have been equally successful in computerized issues and returns. But the real difficulty lies in the automation of acquisition activities. It is forgotten that cataloging begins with acquisition. …
