| Info: | Quality monitoring and error detection in systems is a major step in the testing phase of a system before making it available to the consumer. In new infotainment systems present in luxurious cars, system errors are not accepted and should be avoided. Consequently, a monitoring system should be built to record the data shown on the infotainment screen and an analysis of the data should be done to detect errors and find their sources. One frequent system error is image freezing, i.e. motion stop of the navigation map due to high CPU loads or other error sources. In order to detect such an artifact, the difference image between frames could be used to signal any motion in the frames. When no motion exists, this can mean that either the car has stopped or a freezing has occurred. In order to differentiate between both cases, the map position should be calculated before and after the motion stop, and map jumps could then be detected. For that, invariant points on the map that exist before and after the freeze should be found and map rotations and translations could then be calculated by solving the affine transformation equation. The task of Mr. Khairat is to test different invariant feature detectors and descriptors such as Harris, SIFT, SURF, and FAST, and compare their performance when used for tracking of translating and rotating navigation maps considering different map display styles. Two performance criteria have to be tested: the robustness of the features after rotation and translation of the map, and the computation time for each detector/ descriptor. Additionally, Mr. Khairat has to implement a method to select the best feature points and track the motion of the map. He will have then to test his algorithm on different navigation sequences (with and without freezing) and report its performance for various map jumps. The algorithms have to be implemented in MATLAB and a clean documentation of the work and of the source code will be highly assessed. Betreuer: Gilbert |
