help : bitmap similarity measure

[Niranjan Avadhanam]

Hi,

are there any statistical measures (or other) to compare the similarity
of two bitmaps. an example of the bitmap in question could be:

1 0 0 0
0 1 1 1
0 1 0 0

the dimensionality is important. measures exist - such as the ratio of
the number of matches to the total number of bits, but such measures
ignore the 2D nature of the problem.

please reply to avad...@ece.ucdavis.edu

thanks in advance,

Niranjan
