Automatically determining the size of a blur kernel |
摘要 |
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. |

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. |
