Automatic Axis Shift Alignment #854

Open Hovden opened 7 years ago

Hovden commented 7 years ago

Create a python algorithm to estimate axis of rotation shifting. Target datasets for demonstration are the star nanoparticle and the carbon nanotube.

ok I've found a dumb way that estimates the shift within 1 or 2 pixels accuracy. Works well on star nanoparticle and 180 carbon nanotube. screen shot 2017-02-03 at 5 03 38 pm ----> screen shot 2017-02-03 at 5 04 42 pm screen shot 2017-02-03 at 5 08 53 pm --> screen shot 2017-02-03 at 5 12 43 pm

Seems to work well on those datasets. I look forward to the details of how it works.
