SOFTWARE OR METHOD TO COMPARE SHAPES(CURVES)

[spaggioli]

<br>I have various shapes for form tools that are now receiving a secondary process.<br>This secondary process does not seem to be applied evenly to all surfaces.<br>It does how ever always go on the same if the setup is the same.(the set up is easily controlled). So here is my question does anyone&nbsp;&nbsp;know of a software. That will take the resultant shape and the original shape , compare the two to the theoretical perfect shape, then tell me what the original shape should look like to obtain a some what closer version of the perfect shape. All of the forms are<br>actually curves if this makes any difference <br><br>Thanks in advance<br><br>Scott Paggioli<br>&nbsp;<br>&nbsp;<br>

Such a software could be easy to prepare, depending on the answer you would give to the following question: do you know (or can you guess) the function of transfer that, for a given setup, allows to calculate the shape resulting from any original shape?
If the answer is no, then I suppose this transfer function should be statistically inferred from a number of samples, but some guessed behaviour should still be known or assumed.
Can you give typical examples of resulting shapes together with their originals?
