Patent ID: 8588544

Claim:
A method for reducing ringing artifacts of image deconvolution, comprising: applying a first deconvolution to an original blurred image to obtain a deconvolved image, detecting edges within the deconvolved image, performing edge tapering on the original blurred image, including a strength attenuation of edges within the original blurred image, based on the detected edges of the deconvolved image to obtain an edge-tapered image, applying a second deconvolution to the edge-tapered image to obtain a ringing-reduced image, the ringing-reduced image having ringing artifacts, detecting edges within the ringing-reduced image having the ringing artifacts, repeating said edge tapering on the original blurred image based on the edges detected within the ringing-reduced image having the ringing artifacts, and applying a third deconvolution to the edge-tapered result of said repeating said edge tapering to obtain a ring-suppressed image having no ringing artifacts.
