[APG 2.5B1 OSX] RANSAC settings too technical for me

by Judy-A » Sun Oct 10, 2010 7:03 pm

In CP Editor>Settings> Tools>'CP detector quality', there is a setting for Ransac model. The choices are Similarity and Homography.

As an average user, I have no clue what those choices mean or what they might do.

I found this explanation of homography at Wikepedia.org.
" A homography is an invertible transformation from the real projective plane to the projective plane that maps straight lines to straight lines."

Well, I must confess that I'm no more enlightened than before.

Can we please have either non-technical terms or an information panel that explains when to choose each option?

I agree also. Like to try new features but helps to understand what they are supposed to be doing!

Could the Kolor team put together an descriptive overview of the features that are new to 2.5 so users can beta test these with some understanding of what they are testing.

Note: know of http://www.autopano.net/forum/t9203-autopano-engine-v2.5-changelog but a search of that doesn't get a hit on 'homography.'

:rolleyes: ( :rolleyes: ( homography ) ) = :) ... A Google search for homography site:autopano.net will return indications that homography is related to multiple viewpoints. Then an other Google searches for multiple viewpoint site:autopano.net will show that multiple viewpoints feature was previously known as free nodal points feature !

A series of posts about these matters is available on the forum and the site:autopano.net a very valuable Google feature.
