A qualitative approach to camera motion classification

This paper proposed a robust and hierarchical camera motion classification approach based on integrated histogram. First, a motion direction histogram is built, and the information entropy of histogram is employed to classify camera motion operations into scaling operation and non-scaling operation. And then, static and translation operations are distinguished by distribution information of histogram, meanwhile the direction of translation operation is also identified. Experimental results show that the new approach can efficiently achieve global motion estimation. © (2012) Trans Tech Publications, Switzerland.
