Hello,

I'm starting to learn image analysis, I searched online for some dataset of images to use while learning but I found none.

Is any of you aware of some dataset publicly available?

TIA & best wishes

What type of images do you need? I have many time-series tri-color FITS files for flare stars and eclipsing binaries. I could make some available on Google Drive.

Hi Gary,

I'm working on a VPhot feature that will automatically separate tri-color fits files when uploaded.

I need more examples to experiment with.

Can you share some files via your gdrive?

Thx
George

Hi George,

Yes, I can make some tri-color files available via Google Drive. Rough how many images do you need? For example, I have some tri-color files for B Per. A full evening's run is about 12GB of data.

I'll let you know when they are available.

Best regards,

Gary

Share some tri-color images

Hi Gary

I only need a couple to make sure I understand the file structure. 12Gb would be to much!

Send a note to gsilvis@aavso.org

Hi Gary,

thanks for the offer, I just started so I need just some images to get acquainted with the software, ideally a series of images that I can use to build a light curve will fit the bill

thanks again
