A fast Hermite transform

A fast Hermite transform

We present algorithms for fast and stable approximation of the Hermite transform of a compactly supported function on the real line, attainable via an application of a fast algebraic algorithm for computing sums associated with a three-term relation. Trade-offs between approximation in bandlimit (in the Hermite sense) and size of the support region are addressed. Numerical experiments are prese...

Image Deblocking With 2-D Hermite Transform

New method to eliminate block artifact in high compressed images is presented. Here the emphasis is placed on Hermite transform and we also accentuate on pixel near the block boundaries, and, because it is a polynomial transform with a gaussian window that is in a good agreement with human visual processing procedure.

Fourier transform of Hermite interpolatory subdivision schemes

Image fusion with the Hermite transform

The Hermite Transform is an image representation model that incorporates some important properties of visual perception such as the analysis through overlapping receptive fields and the Gaussian derivative model of early vision. It also allows the construction of pyramidal mutirresolution analysis-synthesis schemes. We show how the Hermite Transform can be used to build image fusion schemes tha...

designing a fast locking pll

a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
