A Single Image Deblurring Algorithm for Nonuniform Motion Blur Using Uniform Defocus Map Estimation

Figure 16

Demonstration of the influence of shadow in the image with nonuniform motion blur. (a) Blurred image. (b) Shadow region corresponding to the red rectangle in (a). (c) A gray level signal corresponding to red line in (b). The -axis is the position, and -axis is intensity in gray level. We can observe that shadow region was detected as a blurred object in Figures 14(d) and 14(e). This phenomenon is caused by a gradient intensity as shown in (c).
