摘要:There is an increasing demand in traffic monitoring of densely populated urban areas. In our approach we use a priori information of roads location and focus on vehicle queues detection. In this imagery single vehicles are merged to either dark or bright ribbons and therefore can hardly be separated. The queues can be extracted as lines in scale space using a differential geometric approach. We exploit the fact that vehicle queues show repetitive pattern. This pattern is also observably in width profile of the queues derived from the gradient image. For discrimination of single vehicles the variations of the width profile will be analyzed. The results of processing a panchromatic QuickBird image covering a part of an inner city area are shown
