Geometric Transform Estimator, stuck in endless loop!

Question

Hi

Some inputs to the Geometric Transform Estimator leads to it getting stuck in an endless loop which cannot be interrupted by Ctrl+c.

Any ideas why? I don't know how to debug that error because GTE seams to be unreachable through Matlab's debugger.

There are plenty enough points for GTE and I cannot see any difference between the input values of when it works and when it gets stuck.

Could it happen because of there being a few duplicate matches in the input. And that RANSAC fails if it picks two points that have the same coordinates in one image, and different coordinates in the other?

Here is the input that fails: (M =[x0,y0,x1,y1])

M =

(No obvious reason to close this Question; it could use some cleanup though.)

Thanks Huibao for the updated files to Computer Vision System Toolbox you sent me. I've been running tests for a few days now and everything works fine.
