Re^4: Abstract image registration or feature detection

It seems that we're not on the same page. A picture is worth a thousand words: https://imgur.com/KxH62Sa

Each labeled red point from the reference image corresponds to the same labeled red point on the distorted image. And I know the coordinates for both. Similarly, one blue point on the reference image corresponds to one blue point on the distorted image, but I only know their coordinates on the reference, and I want to find them on the other.

Thanks the image is much clearer. As I said, solve the linear equations° for the red pairs to determine the projection matrix. (well depending one the number of known pairs) Once you have the matrix you can pair the blue ones too.
