Abstract:
One challenging problem confronting developers of motion detection algorithms for video surveillance systems is the problem of distinguishing between coherent and incoherent motion in the surveillance image stream. For example, a robust motion detection algorithm should alarm at the movement of a person walking through the surveillance scene, but should not alarm at the movement of wind-blown foliage in the same scene, even if the total numbers of pixels comprising the respective movements are comparable. Motion detection algorithms that operate in the frequency domain have proven particularly well-suited to distinguishing between these two types of motion. This project developed a Visual C++.NET desktop application for decoding MPEG-4 surveillance video clips into sequences of frame data structures designed to serve as test inputs to various frequency domain motion detection algorithms under development in the Department of Computer Science at SDSU.
