The 2-point gradient algorithm is the default bad pixel correction method. With this algorithm, the two
pairs of pixels above and below and to the left and right of the bad pixel are evaluated. The algorithm
compares the differences between the pixels and chooses the pair with smallest gradient (difference).
It then averages the two adjacent pixels and uses that value for the replacement value. This
algorithm is better at handling bad pixels near a high contrast edge and is the default method. If the
algorithm encounters a situation is cannot solve (for example, an edge or corner) it will fall back on the
nearest neighbor algorithm.
Nearest neighbor uses a simple replacement using an adjacent pixel. The adjacent pixel is picked using
the pattern depicted below. When a bad pixel is near an edge, those search positions are skipped.
