Abstract
The present invention relates to a method for reducing ringing artifacts of image deconvolution. A deconvolution is applied to the original blurred image and edges are detected within the deconvolved image. Then edge tapering on the original blurred image is performed based on the detected edges. The present invention further relates to a system and a computer program product for reducing ringing artifacts of image deconvolution.
Claims22
Method for reducing ringing artifacts of image deconvolution, comprising the steps of
- applying a deconvolution to the original blurred image,
- detecting edges within the deconvolved image and
- performing edge tapering on the original blurred image based on the detected edges.
System for reducing ringing artifacts of image deconvolution, comprising
- a deconvolution unit that applies a deconvolution to the original blurred image,
- an edge detector that detects edges within the deconvolved image and
- an edge tapering unit that performs edge tapering on the original blurred image based on the detected edges.
System according to any of the preceding claims, wherein the deconvolution unit is adapted to apply a second deconvolution to the edge tapered image thereby obtaining a ringing-reduced image.
System for reducing ringing artifacts of image deconvolution, comprising
- means for applying a deconvolution to the original blurred image,
- means for detecting edges within the deconvolved image and
- means for performing edge tapering on the original blurred image based on the detected edges.
A computer program product stored on a computer readable non-transitory medium which causes a computer to perform the steps of
- applying a deconvolution to the original blurred image,
- detecting edges within the deconvolved image and
- performing edge tapering on the original blurred image based on the detected edges.
