Rotationally Invariant Texture Features Using the Dual-Tree Complex Wavelet Transform
New rotationally invariant texture feature extraction methods are introduced that utilise the dual tree complex wavelet transform (DT-CWT). The complex wavelet transform is a new ...

Edge Preserving Image Denoising in Reproducing Kernel Hilbert Spaces
The goal of this paper is the development of a novel approach for the problem of Noise Removal, based on the theory of Reproducing Kernels Hilbert Spaces (RKHS). The problem is ca...

Approximation of the Hilbert Transform on the real line using Hermite zeros
The authors study the Hilbert Transform on the real line. They introduce some polynomial approximations and some algorithms for its numerical evaluation. Error estimates in uniform...

Hilbert transformers with a piecewise-polynomial-sinusoidal impulse response
— Hilbert transformers are one of the very important special classes of finite impulse response (FIR) filters used in signal processing applications. A method is presented to s...

Digital hilbert transformers for FPGA-based phase-locked loops
The phase detector is a main building block in phaselocked loop (PLL) applications. FPGAs permit the realtime implementation of the CORDIC algorithm which offers an efficient solu...
