Fast Reconstruction of SAR Images with Phase Error Using Sparse Representation
In the past years, a number of algorithms have been introduced for synthesis aperture radar (SAR) imaging. However, they all suffer from the same problem: The data size to process is considerably large. In recent years, compressive sensing and sparse representation of the signal in SAR has gained a significant research interest. This method offers the advantage of reducing the sampling rate, bu...
متن کاملSparse and Robust Signal Reconstruction
Many problems in signal processing and statistical inference are based on finding a sparse solution to an undetermined linear system. The reference approach to this problem of finding sparse signal representations, on overcomplete dictionaries, leads to convex unconstrained optimization problems, with a quadratic term l2, for the adjustment to the observed signal, and a coefficient vector l1-no...
متن کاملRobust Estimation in Linear Regression with Molticollinearity and Sparse Models
One of the factors affecting the statistical analysis of the data is the presence of outliers. The methods which are not affected by the outliers are called robust methods. Robust regression methods are robust estimation methods of regression model parameters in the presence of outliers. Besides outliers, the linear dependency of regressor variables, which is called multicollinearity...
متن کاملSimultaneous Registration and Segmentation by L1 Minimization
This paper studies the problem of simultaneously registering and segmenting a pair of images despite the presence of non-smooth boundaries. We assume one of the images is well segmented by automated algorithm or user interaction. This image acts as an atlas for the segmentation process. For the remaining images in the set, we propose a novel L1 minimization based technique, which leverages the ...
متن کاملSimultaneous Segmentation and Registration of MR Images
C. A. Tejos, M. Guarini, P. Irarrazaval Department of Electrical Engineering, Pontificia Universidad Catolica de Chile, Santiago, Chile Introduction In medical imaging studies that analyse the evolution of structures through time, measurements of anatomical parameters must be preceded by a registration and a segmentation process, to provide the location correspondence of equivalent structures o...
