Poor registration of images #72

I successfully downloaded and used make to install this code. However, the image registration is unusable. I am running the code on Windows Subsystem for Linux, running Ubuntu 20.04. I'm running OPNA2608's fork of the code, to get it to work with Halide 10.0. These photos were taken on an Olympus OM-D EM10 Mark II, with the Olympus 45mm f1.8 lens, at ISO 1000, f/1.8, and at 1/400th of a second. I was using the electronic shutter, at about 8.5 frames/sec.

These photos are of a ping pong serve, taken in dim lighting. This is admittedly a hard use case, but Google's HDR plus algorithm handles it well. This is also really when an HDR algorithm is the most useful, to merge together many underexposed photos. Furthermore, the ghosting problems persist in easier situations, but is less evident. I tried merging smaller and larger stacks of photos, but did not notice improvement.

The photos can be found here: https://drive.google.com/drive/folders/1mgXZVcQhCOkAqI2F1SOzMxo1wE_h7Q9W?usp=sharing I am happy to run this on other samples if needed
