# What algorithm is used by FindGeometricTransform? [closed]

Can anyone tell me how the operation FindGeometricTransform[pts1, pts2] works (I mean inside logic of the transformation function), or where can I find such an explanation?

• It’ll be in the Details section of the docs. You can specify a different algorithm via the Method option too so you can check on that as well. – b3m2a1 Jun 25 '18 at 18:10
• I don't know how it works, but since the geometric transforms in question are linear, the problem is expressible in terms of LeastSquares. – Szabolcs Jun 25 '18 at 18:14

From the "Details and Options" section of the documentation for FindGeometricTransform, the available fitting methods are:
