This is the demo source code of the proposed algorithm presented in: "Abandoned Object Detection via Temporal Consistency Modeling and Back-Tracing Verification for Visual Surveillance," in IEEE Transaction on Information Forensic and Security (TIFS) 2015. ,and "Left-Luggage Detection from Finite-State-Machine Analysis in Static-Camera Videos," in International Conference on Pattern Recognition (ICPR) 2014. Kevin Lin, Shen-Chi Chen, Chu-Song Chen, Daw-Tung Lin, Yi-Ping Hung Usage: 0. Run "ObjLeft.exe" 1. Select the input source (video filename/camera). 2. Double-chlick and set the Region-of-Interest. 3. Double-press any key to start detection. Note: 0. This code has been tested on Windows 7. 1. The human detector is NOT YET integrated with the tracking algorithm. 2. The C++ source codes will be available soon! 3. The parameter can be adjusted in "parameter.txt", we will provide a more friendly gui in future.
