电子科线女学光电科学与工程学院 SCHOOL OF OPTOELECTRONIC SCIENCE AND ENGINEERING OF UESTC Restoration The principal goal of restoration techniques is to improve an image in some predefined sense. Restoration attempts to recover an image that has been degraded by using a priori knowledge of the degradation phenomenon. Thus,restoration techniques are oriented toward modeling the degradation and applying the inverse process in order to recover the original image.◼ The principal goal of restoration techniques is to improve an image in some predefined sense. ◼ Restoration attempts to recover an image that has been degraded by using a priori knowledge of the degradation phenomenon. ◼ Thus, restoration techniques are oriented toward modeling the degradation and applying the inverse process in order to recover the original image.
