In this paper, we propose an intelligent recognition system for objectionable image in JPEG compression domain. First, the system applies robust skin color model and skin texture analysis to detect the skin regions in an input image based on its DC and ACs. Then, the color, texture, shape and statistical features are extracted from the skin regions and input into a decisiontree classifier for c...

In order to defend against extraordinary intelligent attacks in the era of rapidly growing information and technology nowadays, effective and efficient intrusion detection models are needed to detect and prevent intrusion promptly. Bayesian network (BN) classifiers with powerful reasoning capabilities have been increasingly utilized to detect intrusion attacks with reasonable accuracy and effic...

Web proxy caching is one of the most successful solutions for improving the performance of Web-based systems. In Web proxy caching, Least-Recently-Used (LRU) policy is the most common proxy cache replacement policy, which is widely used in Web proxy cache management. However, LRU are not efficient enough and may suffer from cache pollution with unwanted Web objects. Therefore, in this paper, LR...

The Service-Oriented Architecture (SOA) demands supportive technologies and new requirements for mobile collaboration across multiple platforms. One of its representative solutions is intelligent information security of enterprise resources for collaboration systems and services. Digital watermarking became a key technology for protecting copyrights. In this article, the authors propose a metho...

In order to use the mobile robot platform for tracking particular moving objects it is necessary to develop intelligent top level control algorithm. In this paper a computational intelligence based object recognition algorithm in robot vision system is presented. The main goal of this research was to enable DaNI robot to recognize the particular Lego NXT robot among other differently shaped Leg...

This paper describes a vehicle detection system based on support vector machine (SVM) and monocular vision. The final goal is to provide vehicle-to-vehicle time gap for automatic cruise control (ACC) applications in the framework of intelligent transportation systems (ITS). The challenge is to use a single camera as input, in order to achieve a low cost final system that meets the requirements ...

Intelligent power quality monitoring systems have become an essential component of high technology and high availability-oriented industries. Most power quality disturbances are non-stationary and transitory and the detection and classification have proved to be very demanding. The first step towards any solution for a disturbance is to recognize the presence of a particular type of disturbance...
