Abstract

Motion detection can play an important role in many vision tasks. Yet image motion can arise from #uninteresting " events as well as interesting ones. In this paper, salient motion is de#ned as motion that is likely to result from a typical surveillancetarget #e.g., a person or vehicle traveling with a sense of direction through a scene# as opposed to other distracting motions #e.g., the scintillation of specularities on water, the oscillation of vegetation in the wind#. We propose an algorithm for detecting this salient motion that is based on intermediate-stage vision integration of optical #ow. Empirical results are presented that illustrate the applicability of the proposed methods to real-world video. Unlike many motion detection schemes, no knowledge about expected object size or shapeisnecessary for rejecting the distracting motion. 1 Introduction Motion detection can play an important role in many vision tasks, especially those related to detection and tracking for surveillan...
