AUTOMATICALLY DETERMINING THE SIZE OF A BLUR KERNEL
First Claim
Patent Images
1. A computer-implemented method, comprising:
- generating a derivative image from an image having a blurred region;
autocorrelating the derivative image and the image to obtain an autocorrelation map;
determining a size of a blur kernel for the image based on the autocorrelation map; and
deblurring the image by deconvolving the blurred region with the blur kernel.

Abstract
A computer-implemented method and apparatus are described for deblurring an image. The method may include accessing the image that has at least one blurred region and, automatically, without user input, determining a first value for a first size for a blur kernel for the at least one blurred region. Thereafter, automatically, without user input, a second value for a second size for the blur kernel is determined for the at least one blurred region. A suggested size for the blur kernel is then determined based on the first value and the second value.

12. An image deblurring system, comprising:
-
a processor; an image module, coupled with the processor, the image module operated on the processor, to access an image having at least one blurred region; and a blur kernel sizing module, coupled with the processor and the image module, to generate a derivative image from the image, autocorrelate the derivative image and the image to obtain an autocorrelation map, and determine a size of a blur kernel for the image based on the autocorrelation map. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
