Convergence of an iterative time-variant filtering based on discrete Gabor transform

چکیده
An iterative time-variant filtering based on the discrete Gabor transform (DGT) has been recently proposed by the authors. In this correspondence, we present a proof of the convergence of the iterative algorithm under a sufficient condition on the analysis and synthesis window functions of the DGT. In the meantime, we show that the iterative algorithm refines the least squares solution.

An iterative algorithm for time-variant filtering in the discrete Gabor transform domain
In this paper, an iterative time-frequency (TF) synthesis/time-varying ltering algorithm in the discrete Gabor transform domain is proposed. A su cient condition is obtained for the Gabor synthesis and analysis window functions so that the iterative algorithm converges. It is proved that under the condition the algorithm converges to a signal that has its Gabor transform located exactly in a de...
متن کاملتشخیص چهره با استفاده از PCA و فیلتر گابور
Methods for face recognition which are based on face structure are among techniques without supervision and produce unfavorable results in the presence of linear changes in images. PCA is a linear transform and a powerful tool for data analysis but does not produce good results for face recognition when there are non-linear changes resulting from changes in position, intensity and gesture in th...
متن کاملDelay Spoofing Reduction in GPS Navigation System based on Time and Transform Domain Adaptive Filtering
Due to widespread use of Global Positioning System (GPS) in different applications, the issue of GPS signal interference cancelation is becoming an increasing concern. One of the most important intentional interferences is spoofing signals. An effective interference (delay spoof) reduction method based on adaptive filtering is developed in this paper. The principle of method is using adaptive f...
متن کاملSimultaneously inpainting in image and transformed domains
In this paper, we focus on the restoration of images that have incomplete data in either the image domain or the transformed domain or in both. The transform used can be any orthonormal or tight frame transforms such as orthonormal wavelets, tight framelets, the discrete Fourier transform, the Gabor transform, the discrete cosine transform, and the discrete local cosine transform. We propose an...
متن کاملIterative learning identification and control for dynamic systems described by NARMAX model
A new iterative learning controller is proposed for a general unknown discrete time-varying nonlinear non-affine system represented by NARMAX (Nonlinear Autoregressive Moving Average with eXogenous inputs) model. The proposed controller is composed of an iterative learning neural identifier and an iterative learning controller. Iterative learning control and iterative learning identification ar...
