Hey image.sc community! 
I have to analyse pictures showing seedlings with ImageJ and I need to measure the length of the seedlings.
This worked perfect for over a year.
But now, after opening/importing one picture or a series, the picture quality is worsened in ImageJ because the pictures are very pixelated then.
This is not normally the case. The quality of the pictures is good - you can check it at the attached photo, the ImageJ version is on the left.
ImageJ problem 1 2021|300x500 …
My pictures are scans in jpg format and I used ImageJ in the last year to analyse them. Never had this problem before.
I don’t know what changed, my system hasn’t been changed (it has no connection to the internet).
I would be very relieved if someone has a solution for this problem because with this kind of pixelation I cannot distinguish enough between the roots or where one root ends next to some other root.
I work with ImageJ 1.52 or 1.53, I tried older versions of ImageJ and Fiji, no change.!
Seems to be the same problem like this:
But for me, the problem is not solved with zooming in. Thats not possible in my case because I need an overview about the seedlings.
Because I don’t know if many of you can see that I asked my question there I decided to create a new thread. Hope that this is okay.
Hope that you have ideas to solve this problem!
Thank you
