how many array elements with a certain value in a row [message #70279]

Does anyone have a nice simple efficient solution to this problem (I
have a simple inefficient solution and a vague sketch in my mind of a
convoluted but probably efficient solution):

I have an image in which many pixels are saturated (=65535, they're
short unsigned). I want to treat each set of consecutive saturated
pixels in a row as a single unit and know how many saturated pixels in
a row there are. So I would like to have a list that contains (a) the
rightmost pixel of each set of consecutive saturated pixels, and (b)
how many saturated pixels there were in the set.

Any suggestions?

-Jeremy.
