abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...

there are different methods of reconstructing hydrologic data. depending on the conditions of the station a particular method can produce the best results. generally, in order to estimate the lost data in a station and its surrounding stations, hydrologic, climatologic and/or physiolographic similarities are used. recently, the fuzzy regression method has been used to reconstract the hydrologic...

Background & objective: Trees, as an influential element, have an important role in post disaster reconstruction in four aspects; they can be used as "temporary settlement materials", "reviving collective memories", "creating calm” and “motivation for reconstruction". In addition, as "living memorials”, they remind the disaster and indicate the necessity of preparedness and resilience of societ...

In this paper, we present a novel approach for reconstructing an object surface from its silhouettes. The proposed approach directly estimates the differential structure of the surface, and results in a higher accuracy than existing volumetric approaches for object reconstruction. Compared with other existing differential approaches, our approach produces relatively complete 3D models similar t...

Image reconstruction using data-dependent triangulation" (2001). All Faculty Publications. Paper 571.

Introduction: While the necessity of replacing voxels with blobs in conventional tomographic reconstruction based upon line-integrals is clear, it is not however well-investigated in plane- integral-based reconstruction. The problem is more challenging in convergent-plane projection reconstruction. In this work, we are aiming at utilizing blobs as alternative to voxels. <stron...
