Combining Metrics

  1. Jun 5, 2008 #1
    I have two measurements:

    1) overlap - how much do two shapes overlap
    2) distance - for the part that does overlap, how similar are the two shapes?

    Overlap is clearly a percentage, from 0 percent to 100%.

    Distance can be from 0 (exactly the same) to (theoretically) infinity.

    Now what I need to do is give some metric for "good" in a single number, where "good" is high overlap and low distance. It seems like there is some arbitrary multiplier needed when you combine these two measurements, does anyone have any pointers on how to do this "properly" (or at least justifiably)?

    Thanks!

    Dave
