| 摘要 |
Deblurring a blurry image (14) includes the steps of (i) computing a spatial mask (256); (ii) computing a modified blurry image (264) using the blurry image (14) and the spatial mask (256); and (iii) computing a latent sharp image (16) using the modified blurry image (264) and a point spread function (260). Additionally, the image (714) to can be analyzed to identify areas of the image (714) that are suitable for point spread function estimation. Moreover, a region point spread function (1630) can be analyzed to classify the point spread function(s) as representing (i) motion blur, (ii) defocus blur, or (iii) mixed motion blur and defocus blur. A point spread function (2670) can also be estimated |

1. A method for deblurring a blurry image having a point spread function, the method comprising:
computing a spatial mask for the blurry image with a control system that includes a processor; computing a modified blurry image with the control system using the blurry image and the spatial mask; and computing a latent sharp image with the control system using the modified blurry image and the point spread function. |
