Dynamic Selection of Characteristics for Feature Based Image Sequence Stabilization

摘要

In this document, we deal with the problem of video cameras operating outdoors where the atmospheric conditions and the vibration caused by vehicles passing by make it difficult to sustain the assumption of a fixed camera. Under these circumstances, a method like ours, that dynamically chooses the features that support the transformation from frame to frame, is different to others that fix the features that are tracked. That is because, for vehicular traffic monitoring applications, there are features that appear or disappear as time passes by. This contributes to the flexibility and capability of adaptation of the method to different scenarios. To test the algorithms, we used several image sequences of a camera, experiencing heavy motion due to wind and/or vibration due to vehicular traffic.
