Elevation profile app
April 1, 2017 – Present
This application plans routes and show the elevation profile along it. Enter origin and destination, the app will automatically plan route and show the elevation profile along the route. You can also long tap on the map to set origin and destination.
Intelligent Vision Analysis
October 1, 2013 – Present
Developed robust motion detection algorithm based on compressed-domain input data. The algorithm must support full-HD, runs under limited memory (~a dozen KB) and limited computing power. Features such as multiple ROIs, adjustable sensitivity, adjustable object size to be detected are also implemented. Several test cases are also designed to show the performance of the algorithm.
