An image restoration problem commonly encountered in many branches of science and engineering is that of removing the effects of uniform object motion. If the direction of object motion is not orthogonal to the line of sight of the imaging device, an image with both nonuniform motion blur and perspective may be produced so that the usual assumption of a space-invariant linear operation is no longer valid. In this paper we show that a proper initial geometrical transformation reduces the problem to one which can be handled by standard methods for removing uniform motion blur. As will be demonstrated, the process is strictly valid for planar (2-D) objects only. For objects with depth, residual space-variant blurs still exist. We highlight through examples several practical aspects of digitally deblurring such objects, including proper geometrical transformations, initial blur estimation, and residual space variance.
