Title:
SELF-REGULARIZING INVERSE FILTER FOR IMAGE DEBLURRING
Document Type and Number:
WIPO Patent Application WO/2022/181998
Kind Code:
A1
Abstract:
A method includes capturing, by a camera disposed behind a display panel of an electronic device, an original image through a semi-transparent pixel region of the display panel. The original image is associated with one or more predetermined point spread functions (PSFs) and includes one or more blurring artifacts. The method further includes estimating an optimal regularization parameter for the original image based on the one or more predetermined PSFs and the one or more blurring artifacts, applying a self-regularizing inverse filter, such as a fast self-regularizing inverse filter, to the original image based on the estimated regularization parameter, and generating a deblurred image based on the self-regularizing inverse filter. Generating the deblurred image includes reconstructing the original image utilizing the self-regularizing inverse filter to remove the one or more blurring artifacts.
