I’m not sure if I understand. Images 2 and 3 in the first row look the same as images 1 and 2 in the third row, right? The only difference is they are not saved (1st row) and saved+reloaded (3 row). I see no issue here.
Yes, image 2 and 3 in the 1st row are exactly the same as image 1 and 2 in the 3rd row.
I just wanted to show you how they were presented as soon as the NLM is finished in the 1st row
without doing anything else. They were not (yet) saved at the moment.
I do not know why these images are shown like this. When working with scientific images, I recommend using Fiji for displaying them and no software such as Microsoft Paint or the Windows Photo viewer. Fiji is made for scientific image analysis, the others are not.
Although I do agree with you, the differences look very strange. I have never seen
such a HUGE difference between images that were open using Fiji or using the
basic softwares that comes with Windows. I did see some differences in other occasions
in the past, but this one specifically seemed way to different to ignore.
Another thing that caught my attention is that the image shown by Windows, albeit different
from the NLM CPU one, seems to be more similar than the one shown by Fiji just after using
the NLM GPU plugin.
So I’m not sure why this happens either, and if I’m the only one. I did delete Fiji entirely
and began from scratch, but it seems this issue doesn’t go away. Since this happened
with the GPU NLM, I figured that it might be some issue with the plugin, but it is strange
that after saving the image, it seems to change that too in some way that doesn’t happen
with the other images.
Is it possible that it might be some issue with the image itself? Because I just tried using
the NLM CPU vs GPU in two other images, and this bizarre effect did not happen. The
Windows and Fiji images seemed pretty similar.
