Haar feature based cascade classifiers and duplex flexible window

Hi can someone tell me the purpose of AdaBoost classifiers? Is the Harr feature based AdaBoost classifier same like normal classic AdaBoost classifiers? I have a project in which this method of Harr feature based classifier is used to detect the tail lights and brake lights of a vehicle in the paper named "A robust detection method of vehicle queue and dissipation during evening rush hours".Another method is also used in this paper to maintain a window for queue length named Duplex Flexible Window.If anyone have idea about these two methods or used some where,so please help me i shall be very thankful.

Sorry, I am not going to look at the paper you mention. FWIW, I suspect that Harr features is what you extract from an image using tools appropriate for image analysis. Then you apply the standard well-known AdaBoost algorithm to these extracted features. I am not an expert on image processing and cannot advise you on extraction of Harr features. But I can tell you that AdaBoost is provided in the Statistics Toolbox in 11a in fitensemble function.

yes i have that code but i am unable to understand the code and the parameters bla bla....if you have some idea that how to use it i shall be very thankful...:)

can you please provide me the code as I am doing a project on real time vehicle detection using haar cascades
