Functions perform image deconvolution. They can be used for restoring the degraded image, in particular image that was obtained by applying the convolution operation with known kernel.
(Iterative method) [Ric72]. Border pixels of a source image are restored before deconvolution.
For further reference to the Lucy- Richardson method:
W.Richardson. Bayesian-Based Iterative Method of Image Reconstruction. Journal of the Optical Society of America, vol.62, No.1, January 1972.
Note that to deconvolve an image, the image should NOT be saturated.
Example of blurred image
After applying the deconvolution, some details now appear clearer.
