- W2084014815 abstract "Abstract Image intensity and edge are two major sources of information for estimating motion in the image plane. The 2-D motion obtained by analyzing the deformation of intensity and/or edges is used to recover the 3-D motion and structure. In this paper we show that the motion defined by the image intensity differs from the motion revealed by the (zero-crossing) edge. Understanding of this discrepancy is important since most of the 3-D motion recovery algorithms reported so far require accurate 2-D motion as their input. We begin the discussion by assuming the invariance of intensity, that the evolution of image intensity manifests the underlying transformation of the image due solely to the motion of objects. We then raise the question whether the zero crossing of the Laplacian operating on the image intensity is invariant too. The change of perspective view due to relative motion results in the zero crossing not being preserved as the image evolves. We derive how much the zero-crossing contour deviates from its “correct” position due to motion. Our analysis shows that the deviation is inversely proportional to the third derivatives of image intensity. The result may be used to determine the agreement between the motion obtained from the zero-crossing contours and from the intensity Change." @default.
