An efficient people tracking system using the FFT-Correlation and Optimized SAD

The research questions which this study addresses are resumed in obtaining the picks of Optimized SAD and FFT-Correlation function. These values allow us to detect and track the blocs corresponding to the moving person. This Bloc-Matching system of our tracked bloc 8x8, simplify the process of detecting and tracking all the representative matrix of foreground. Practically, in this correspondence, we propose an implementation technique for detection and tracking system which detect and track people's in motion using a fixed single camera. These bi-techniques simplify the process of people tracking and give a new way for people tracking. Moreover, in this system we choose to detect moving people with the more robust algorithm (Gaussian Mixture Model) in term of misclassified pixels. Thereafter, we track a bloc 8x8 from the bounding box containing the moving person by returning the position of the similar bloc in the next frame. This bloc position is detected by maximization of the Fast Fourier Transform-Correlation (FFT-Corr) and minimizing the error: optimized Sum of Absolute Difference (OSAD) between the bloc reference and the similar bloc. © 2005 - 2013 JATIT & LLS.
