Image deblurring using empirical Wiener filter in the curvelet domain and joint non-local means filter in the spatial domain
In this paper, an efficient image deblurring algorithm is proposed. This algorithm restores the blurred image by incorporating a curvelet-based empirical Wiener filter with a spatial-based joint non-local means filter. Curvelets provide a multidirectional and multiscale decomposition that has been mathematically shown to represent distributed discontinuities such as edges better than traditiona...
متن کاملImage Deblurring using Split Bregman Iterative Algorithm
This paper presents a new variational algorithm for image deblurring by characterizing the properties of image local smoothness and nonlocal self-similarity simultaneously. Specifically, the local smoothness is measured by a Total Variation method, enforcing the local smoothness of images, while the nonlocal self similarity is measured by transforming the 3D array generated by grouping similar ...
متن کاملImage Denoising Method Using curvelet Transform and Wiener Filter
A new image denoising method based on curvelet transform is proposed. The limitations of commonly used separable extensions of one-dimensional transforms, such as the Fourier and wavelet transforms, in capturing the geometry of image edges are well known. Here, we pursue "true" two-dimensional transform that can capture the intrinsic geometrical structure that is key in visual information. Deno...
متن کاملA fast wavelet algorithm for image deblurring
We present a nonlinear fully adaptive wavelet algorithm which can recover a blurred image (n × n) observed in white noise with O(n2(log n)2) steps. Our method exploits both the natural representation of the convolution operator in the Fourier domain and the typical characterisation of Besov classes in the wavelet domain. A particular feature of our method includes “cycle-spinning” band-limited ...
متن کاملPassive Power Filter Design Using Genetic Algorithm
Continuous technological development facilitates the increase in the number of nonlinear loads that significantly affect the power quality in a power system and, consequently, the quality of the electric power delivered to other customers. One of the most common methods to prevent adverse effects of nonlinear loads on the power network is the use of passive filters. Design of such filter can be...
