More and more low level vision algorithms are being carried out in the spatial frequency domain, using Gabor lters. There are two basic problems concerned with Gabor lterings we will address in this paper. One is the window size problem, in which we will adopt a set of 2D variable window Gabor lters, and compare its performance with those of xed window lters. We will show that the variable wind...

‎We present an application of the dual Gabor frames to image‎ ‎processing‎. ‎Our algorithm is based on finding some dual Gabor‎ ‎frame generators which reconstructs accurately the elements of the‎ ‎underlying Hilbert space‎. ‎The advantages of these duals‎ ‎constructed by a polynomial of Gabor frame generators are compared‎ ‎with their canonical dual‎.

Abstract Origami-inspired approaches to deployable or morphing structures have received significant interest. For such applications, the shape of origami structure must be actively controlled. We propose a distributed network embedded actuators which open/close individual folds and present methodology for selecting positions these actuators. The deformed is tracked throughout its actuation usin...

we consider gabor systems generated by a gaussian function and prove certain classical results of paley and wiener on nonharmonic fourier series of complex exponentials for the gabor expansion‎. ‎in particular, we prove a version of plancherel-po ́lya theorem for entire functions with finite order of growth and use the hadamard factorization theorem to study regularity‎, ‎exactness and deficienc...

-Nowadays face recognition plays an important role in today’s world. It has achieved greater importance in the field of information security, law enforcement and surveillance. Now this face recognition approach is applied to many areas like Airport security, Driver’s License, Passport, Customs and Immigration. In face recognition Local appearance based methods had achieved greater performance. ...
