Fig. 6.
Comparisons of physically/computationally in-focus and physically/computationally defocused images. (a) and (e) are physically defocused images, and (b) and (f) are corresponding computationally refocused images. (d) and (h) are physically in-focus images, while (c) and (g) are computationally defocused versions of these images. The white-box insets are the magnified images of the black-box regions. The black arrows indicate the polarization artifacts. Yellow boxes denote four manually selected areas with a 15
