I believe the idea is that mapping isInteresting over pixels will produce a lazy sequence of true/false values, eg. (true true false ...) or, if it returns a measure of the interestingness of a pixel, (0.75 0.32 nil ...). Then, the filter on identity will strip out any* false/nil values, leaving only the interesting pixels to count.
