| Summary: | This article presents a new method for detecting moving objects in fixed cameras that undergo unexpected motion due to vibration. In our approach, the vibration is automatically compensated for using a dynamically-selected set of trackable features, computing frame-to-frame homographies while preventing numerical degeneracy. One of the most noteworthy characteristics of our method is its ability to withstand occlusions. The robustness of the method is demonstrated in situations where a monitoring camera is subject to vibrations due to inclement weather conditions, such as rain or wind, or other outdoor operating conditions, including vehicles passing nearby. |
