    1. The company, in collaboration with Alcatel-Lucent, participated in the Taipei City Police Department’s Roadside and Neighborhood Intelligent Surveillance System tender on 29 June 2009. I was responsible for six algorithm competition tasks, and achieved a perfect score in the algorithm competition section. I independently conducted the research and development of these six algorithms from 24 July 2008 to 29 June 2009. All of these algorithms were designed for real-time video analysis.
       1. Forbidden Area: When an object enters a user-defined area, the algorithm detects it and triggers an alert with a recorded video clip of the event.
       2. Forbidden Line: Users can freely define alert lines on the surveillance screen. Once an object crosses an alert line, the algorithm detects it and outputs a warning message with a recorded video clip of the event.
       3. People / Car Counting: The algorithm detects people and vehicles and counts their numbers on the road. In addition, it records movement directions and stores all related event information.
       4. Unattended Object: In a surveillance video system, when an object remains in a fixed position for longer than a user-defined period, the algorithm marks the object, including its size and position.
       5. Car Color Detection: To search for suspicious vehicles in surveillance video, the algorithm uses vehicle color features to reduce search time. It can detect user-defined colors and records vehicle information, including appearance time, color information, and snapshots.
       6. Car Direction: Users can define the object tracking direction to be detected. When an object's direction matches the user-defined direction, the algorithm marks the object and records the corresponding directional information.
    2. Developed a vehicle license plate localization function for the Hualien County Police Department in Taiwan, enabling faster vehicle searches in surveillance video and significantly reducing search time.
    3. Developed fourteen intelligent video surveillance algorithm prototypes within five months, including Missing Object Detection, Motion Detection, and Flame Detection.
