ABSTRACT

All convolution-related topics have been covered in earlier chapters except image restoration and the underlying mathematics of deconvolution; these will be discussed in this chapter.

Images are produced in order to record or display useful information. No image information is perfect because of inherent physical and technological limitations. With the ever-increasing demand for improvement in the quality of digital images, there is a need to correct errors caused by the imaging system. ese errors have many causes, including the hardware; insertion of additive or multiplicative noise by both human and

other sources; and blurring of the image by linear motion of the imaging equipment or misalignment, causing defocusing.
