Coupling BM3D with directional wavelet packets for image denoising

Autor: Averbuch, Amir, Neittaanmaki, Pekka, Zheludev, Valery, Salhov, Moshe, Hauser, Jonathan

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 and its corresponding transforms are designed in [1]. The denoising alg

Image inpainting using directional wavelet packets originating from polynomial splines

Autor: Averbuch, Amir, Neittaanmaki, Pekka, Zheludev, Valery, Salhov, Moshe, Hauser, Jonathan

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 (qWPs) which originate from polynomial splines of arbitrary orders. Ten

Nonlinear analysis of the classical phase-locked loop (PLL) is a challenging task. In classical engineering literature simplified mathematical models and simulation are widely used for its study. In this work the limitations of classical engineering
