Similar to that in Eq. (10.9), x

t
here represents the ith pixel in the neighborhood of
the T-candidate. Thus, the source pixel that has the most similar neighboring values
to the target one will be selected as the T-candidate.
In fact, the two diffusions, or S-candidate selection and T-candidate selection,
are simultaneous and competitive. These two candidates have to compete with each
other and only one of them will be chosen to fill-in the target pixel. Normally, if
target pixel nears edge, the choice will bias to the S-candidate. In addition, it can be
observed that long-distant parallel diffusion of structural ...
