stitching

[Jojo l'asticot]

Hello

i work on a stitching interferometry project. i build the topographies of all the parts of a miroir and i need to stick them together in order to display the global topography of the mirror. (the different topographies are taken along a same direction)

Each topography is a 2D array (1020*1024). how can i search the similar zone between two images? i think intercorelation may be a good idea but i don't know how realize it.

Could you help me?

Thank you

Jordan

Are you trying to stitch 2 arrays together removing overlap?  The easiest way to find the ideal match is to look for the minimum overlap between the edges.  Lest assume only 1 degree fo freedom if you have 2 arrays of 1024x1024 called A and B look at the average differency between overlapping n columns the right most  (1024) from A and left most (0) form B increase n from a value of 1 until you find the minimum value, this corresponds to the stitch location.  Then join A and B, remove n columns from either the high end of A or the low end of B, best might be to remove from both and replace with the everace value of both removed regions.
