can anyone guide me to good websites with respect to this topic "image deblur without original image"
I have gone through a number of papers and codes for a week.
all examples had codes which took a original good image added a blur function & then deblurred that image.
I dont have orginal image but have a deblurred image. Looking for sample code C or matlab to start off with.
