Wavelet-Based Homomorphic De-Speckling Technique With Directional Weighted-Averaging Stage

Weighted Directional 3D Stationary Wavelet-based Action Classification

The aim of intelligent surveillance is to conceive reliable and efficient systems having the ability to detect moving objects in complicated real world scenes. These systems also, track the detected objects and analyze their actions and activities. Many applications are built on these operations such as advanced robotics and human computer interaction. This paper aims at proposing a framework f...

Medical Image De-speckling Based on Improved Polar Coordinate

In recent years, medical image processing has been a hot issue for researchers at home and abroad. Considering the characteristics of medical image collection and speckle noise distribution, a de-speckling algorithm based on an improved polar coordinate is present in this paper. Firstly, a logarithmic transformation is applied to the noisy medical image in polar coordinates system and then full...

Research of Signal De - noising Technique Based on Wavelet

During the process of signal testing, it is often exposed to interference and influence of all kinds of noise signal, such as data collection and transmission and so noise may be introduced. So in practical applications, before analysis of the data measured, the need for de-noising processing. The signal denoising is a method for filtering the high frequency noise of the signal and makes the si...

ADAPTIVE ORDERED WEIGHTED AVERAGING FOR ANOMALY DETECTION IN CLUSTER-BASED MOBILE AD HOC NETWORKS

In this paper, an anomaly detection method in cluster-based mobile ad hoc networks with ad hoc on demand distance vector (AODV) routing protocol is proposed. In the method, the required features for describing the normal behavior of AODV are defined via step by step analysis of AODV and independent of any attack. In order to learn the normal behavior of AODV, a fuzzy averaging method is used fo...
