Method1 (Average/Copy Adjacent) – the algorithm consists of averaging the adjacent pixels
when replacing a single defect and copying the nearest pixel when replacing two consecutive
defects or a defect at the beginning or end of a line, i.e.
A= pixel A
B= pixel B
X= defect
AXB is corrected to ACB where:
C= (A+B)/2
AXXB is corrected to AABB
XA is corrected to AA
BX is corrected to BB
Method3 (Average/Weighted Average) is a custom enumeration. algorithm consists of
averaging the adjacent pixels when replacing a single defect and performing a weighted
average when replacing two consecutive defects. A defect at the beginning or end of a line
is not corrected, i.e.
A= pixel A
B= pixel B
X= defect
AXB is corrected to ACB where:
C= (A+B)/2
AXXB is corrected to ACDB where
C = (11 *A + 5*B)/16
D = (5*A + 11*B)/16
XA is not corrected
BX is not corrected

Notes
Performs pixel defects calibration. This is a cumulative function (i.e. defects are added to the
current defect map).
For each pixel:
