I was hoping someone could provide a reference for understanding the
precision associated with spatial measurements, e.g., areas and their
boundaries. For example, assume I have a high resolution image of a black
blob. The number of pixels that make up the black blob is 1 million.
(1) What is the precision assiciated with its area if I count the pixels?
(2) How would the precision be affected if I reduced the image resolution
by half, by a quarter, etc.? (which would reduce the blob's pixels to
250000, 62500, respectively)
(3) Similarly, how would similar resolutions affect the precision of the
blob's boundary measurement?
I don't mind this beginning a discussion, but I'm primarily after a
reference I can cite.
TIA & cheerios :o)
