Using AI for imaging

Recommended Posts

Hi People,


Has anyone used machine learning to help with imaging, eg guiding and PEC or aligning and stacking, picking out faint images etc?


Also I'm thinking focusing, drizzle and dithering.

What are people's thoughts?


Regards

Steve.

Define what you mean by AI ??  its' a very hip\misused\understood term for manipulation of computer data (of any source\type) to try & enforce a required output, so all of us that use guiding, plate solving, imaging etc. uses AI

Well I'm using open CV feature detector to help me to focus. It automatically chooses a star and then I use ordinary python code to adjust the focus, feed it back into open CV again and open CV gives me a HFD-like update.

I thought that some sort of machine learning of the sort that Google do with their stuff like tensorFlow might speed it up and avoid me having to try algorithm after algorithm to find the optimal case.

So from your example, if you recorded the exact focus position, each time you go through the process, and used that data as a starting point for the routine, then you would be using a basic form of AI...

Plate solving works on the basis of a database of stars, combined with a knowledge of where the mount needs to be pointed from its' starting point, and iteritivly takes an image of where the mount is pointing and compares this image with the database, and adjusts the mount to match the database and local image....

All you would be doing by trying to include a large corporate in the process, would be to give them the ability to target you with appropriate advertising on your obvious preferences.... no thanks....

There are some positive results with regards to image enhancement already.

It won't be much longer before the same type of convelutional networks can generate higher resolution results. A few recent papers came out about dynamically growing networks during training, rather than starting with a high res image from the start.

Beyond image enhancement, I suspect that we will see someone come up with a full image guiding approach. Using some kind of recurrent neural network to determine which direction your mount needs to move in to stack locked on a target.
