Birds Eye View / Homography using OpenCV

When I looked for a small example for a homography transformation using OpenCV in order to provide a birds eye projection of an image. I did not find an appropriate ones, hence, I combined a number of motivating introductions and code fragments in an illustrative small program. It can be adapted for your actual purpose…


Bidirectional Graph-Search: A Benchmark

A Bidirectional Graph-Search Algorithm We had some trouble with the slow identification of “simple paths” and “shortest paths” in our application, whereby we applied the common networkx library for python. We therefore developed our own bidirectional path search algorithms, for which we want provide a small benchmark at this post. The algorithms can be downloaded…
