This code is developed to compute the image connectivity graph to guide the structure from motion SfM for image correspondences.
It is based on having a sparse point cloud and initial image orientation. The example attached in the file is a part of my PhD. research at Twente university - ITC. Rate the code if you find it useful.

Hi Bashar Alsadik,

It seems like an nice research contribution.

But, I tried your code. It has shown the error:
Undefined function or variable 'HPR'.

Please fix it.

Thanks

John
