3.15 Consider the images and inpainting regions in Figure
3.45
. Explain why,
using PDE-based inpainting, the inpainted region will be identical in both
cases. (For more investigation of this issue, see [
273
].)
3.16 Determine the white point in Figure
3.21
with the highest inpainting
priority, given the labeled confidence and data values.
3.17 Determine a target region
such that every pixel on the fill front for patch-
based inpainting has the same confidence term.
3.18 Construct an image and inpainting region for patch-based inpainting that
contains both a point with a very high confidence term and a very low data
term, and a point with very high data term and a very low confidence term.
