Hi Eran,

there are a lot of ways of filling missing pixels... one of them is to
have a 3*3 (or else) window that moves over your image. When the central
pixel is a "missing" one, get the value of the pixels in the window and
assign the majority value to the missing pixel... this works well for
classification, you might want to do an average instead if you have
continuous values.

The trick is not to assign the missing value to any pixel, even if it is
the majority value, so you would have to iterate it several times... And
of course, your window doesn't need to move over the whole image, just
select the missing pixels via Where().
