image connectivity graph - SfM

This code developed to compute and visualize the connectivity between images in SfM

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.
