Abstract
A method of image restoration for certain systems with space-variant point-spread functions is presented. The technique, called coordinate transformation restoration (CTR), is applicable to a large class of optical degradations, and operates by first transforming the degraded image by a geometrical distortion. Following this, space-invariant inverse filtering or estimation and another transformation are used to complete the process. The CTR technique makes restoration practical for a variety of incoherent systems with motion and aberration degradations by effectively reducing the system dimensionality.
