i have a sets of images A
Each image (a_i) is a slice of an huge computer generated map-image M_A. Each image a_j in A overlaps with at least one other image a_k in A. There is no distortion, blur or color difference they overlap pixel perfect and are completely planar.
i need to stitch them together = map M_A.
After that i need to find the difference between M_A and an other map-image M_B (gimp)
the last part is no problem: I can put them in 2 layers in Gimp an set one to 'Differece'
the tricky part is the lossless stitching
so:
- How do i stitch the overlapping images together without blurring or deformation?
i tried Hugin (How to make a cyclorama) - i like it - but it seems it is all about inexact images (taken by Cameras). It forced me to choose a focal length. And after 3h of computation i ended up with a projection of planar objects on a sphere, witch were then projected back to a plane for rendering...
