Title of the lecture: Limitations in Image and Signal Restoration
Keywords: Deblurring, Linear Model, Ill-posed problem, Spectral filtering, Regularization
Summary: Recovering the original image or signal from corrupted one, is demanding task and a mathematical model of the blurring process is needed. The key issue is that some information is “hidden” and can be recovered if some a priory information is known. Because of existing unavoidable errors in recorded signal or image, there is not hope to recover them exactly. So, different regularization methods are introduced to get some approximation of the original. Limitations of such methods are analysed.
