Cross-boosting of WNNM Image Denoising method by Directional Wavelet Packets
Amir Averbuch, Pekka Neittaanmäki, Valery Zheludev +2
The paper presents an image denoising scheme by combining a method that is based on directional quasi-analytic wavelet packets (qWPs) with the state-of-the-art Weighted Nuclear Nor…
Directional wavelet packets originating from polynomial splines
Amir Averbuch, Pekka Neittaanmaki, Valery Zheludev
The paper presents a versatile library of quasi-analytic complex-valued wavelet packets (WPs) which originate from polynomial splines of arbitrary orders. The real parts of the qua…
Coupling BM3D with directional wavelet packets for image denoising
Amir Averbuch, Pekka Neittaanmaki, Valery Zheludev +2
The paper presents an image denoising algorithm by combining a method that is based on directional quasi-analytic wavelet packets (qWPs) with the popular BM3D algorithm. The qWPs a…
Image inpainting using directional wavelet packets originating from polynomial splines
Amir Averbuch, Pekka Neittaanmaki, Valery Zheludev +2
The paper presents a new algorithm for the image inpainting problem. The algorithm is using a recently designed versatile library of quasi-analytic complex-valued wavelet packets (…
A posteriori error estimates for time-dependent reaction-diffusion problems based on the Payne-Weinberger inequality
Svetlana Matculevich, Pekka Neittaanmäki, Sergey Repin
We consider evolutionary reaction-diffusion problem with mixed Dirichlet--Robin boundary conditions. For this class of problems, we derive two-sided estimates of the distance betwe…
Effect of magnetic field on resonant tunneling in 3D waveguides of variable cross-section
L. M. Baskin, B. A. Plamenevskii, O. V. Sarafanov
We consider an infinite three-dimensional waveguide that far from the coordinate origin coincides with a cylinder. The waveguide has two narrows of diameter . The narr…
