Intelligent Data Analysis deals with the visualization, preprocessing, pattern recognition and knowledge discovery tools and applications using various computational intelligence techniques. The ten papers included in this special issue represent a selection of extended contributions presented at the 6th International Conference on Hybrid Artificial Intelligence Systems (HAIS), held in Wroclaw,...

Detrended fluctuation analysis (DFA) is a scaling analysis method used to estimate long-range power-law correlation exponents in noisy signals. Many noisy signals in real systems display trends, so that the scaling results obtained from the DFA method become difficult to analyze. We systematically study the effects of three types of trends--linear, periodic, and power-law trends, and offer exam...

This paper presents various algorithms for motion detection, object classification, object tracking and action recognition. It is an essential benchmark in the fields of video surveillance, traffic monitoring, border security etc. A novel approach is presented for detecting vehicles and pedestrians based on haar features. Haar feature value is calculated by using the rectangle integral, each re...
