Calculating The Image Flow Field Of A Moving Planar Surface Under Perspective Projection

The image of an object under perspective projection change with time when the object is moving and rotating. These image changes called image deformation, provide important information which can determine the image flow. In this paper, the change in the relative positions of linear structures in two consecutive images as a consequence of deformation are analyzed. Various components of deformation are used to calculate the flow parameters of a moving planar surface.
