Title: Improving chunk alignment
Post by: patcarbon on November 17, 2011, 03:53:56 PM
For my type of Images, I've found that the automated chunk alignment can give bad results.  There are many similar features, and the system I'm looking at even has some fractal characteristics so cross-scale similarities exist.

So I was wondering if the following is possible:
1-  Manually align the chunks with 3 markers.
2- Optimise this alignment, hopefully to sub-pixel accuracy, with an automated match run.

So I'm hoping that with 2 approximately aligned chunks, the pattern match algorithm will limit it's search area via some sort of epipolar constraints and thus reduce false positive matches.  Can this be done in 8.4?

Hello Patrice,

We are working on improvement of the chunk's align functionality, but no changes about that are expected in 0.8.4.
