Construction of a phase-inverting grating and its use in a deblurring filter.
A method of generating phase-inverting grids for use in image deblurring is described. We have also made an amplitude filter for correcting motion blurred images. This was used along with the phase-inverting grid to deblur motion blurred pictures. Experimental results are presented. It is shown that increasing the noise term in a Wiener filter helps in the reduction of noise but occasions loss of resolving power.
