The study is based on the real-time dynamic gesture recognition in computer vision technology.And it designs aapplications about PowerPoint control based on the technology in multimedia teaching using OpenCV vision library in theVS2010platform.First,using the background subtraction method,the hand gesture detecting motion gesture area through the background difference diagrams and color histogram back projection figure detected on the basis of the background update,can achieve more satisfactory detection results of real-time motion.Secondly,gesture tracking using particle tracking algorithm based on color histogram,basically meet the real-time tracking.Finally,using the contours-matching method that based on Hu moments,this method can bring to a satisfactory conclusion.And the application of controlling PowerPoint uses six gestures,can meet the requirements of the application.
