Fourier Transform using Spring-Mass System

Image Morphing Using Mass-Spring System

A fast and efficient deformation model is essential for realistic simulation of image morphing. In order to create models that are fast to simulation, we use a mass-spring system, which is applied widely in the real time animation of deformable objects. One-to-one deformation is one of the important issues in image morphing. We propose a method of detecting and removing overlaps in the process ...

Deformable Image Registration using Spring Mass System

The paper describes a novel multi-resolution registration method. It is fast, robust and offers high registration accuracy. The algorithm models deformations using an elastic spring mass system, which contains sparse masses interconnected by springs. The proposed method uses data intensity values to guide deformation with local constraints imposed by interaction of interconnecting springs. More...

Using the Fourier Transform

We give a quantum algorithm for solving a shifted multiplicative character problem over Z/nZ and finite fields. We show that the algorithm can be interpreted as a matrix factorization or as solving a deconvolution problem and give sufficient conditions for a shift problem to be solved efficiently by our algorithm. We also show that combining the shift problem with the hidden subgroup problem re...

Intrusion Detection System Using Discrete Fourier Transform with Window Function

An Intrusion Detection System (IDS) is countermeasureagainst network attack. There are mainly two typesof detections; signature-based and anomaly-based. And thereare two kinds of error; false negative and false positive. Indevelopment of IDS, establishment of a method to reduce suchfalse is a major issue. In this paper, we propose a new anomaly-baseddetection method using Discrete Fourier Trans...
