Hi,
The tutorial below is temporarily available (it will not exist permanently on my Google Drive...I was just trying to help the user below).
It will be released in forthcoming tutorials I will be making available.
Just wanted to give forum users a chance to see it.
From Mikey2000 in this thread:

Adam (ngc1535) thanks for your message with the video:
https://drive.google.com/open?id=1KPWBDrVMByq0xb8PnZc-JOSrxDWIdiz2I tried your technique and it worked very well. Now, I'm a newb with PI but I still managed to follow the steps and even learned a few new things along the way.
The blobs in your video are very similar to the blobs I experienced. I'd recommend anyone to take a look.
In summary, Adams technique is as follows.
Quick PixelMaths to create a mask from pixels that are way more red than they are green/blue
Dilate the mask a little
MultiscaleMedianTransform on the R layer to patch over the blobs
(optional) Noise Generation on the patches to match the background.
The process worked on my blue blobs as well with only minor adjustment to the pixelmaths formula.
I suppose the ultimate goal is to create a stack without any blobs in the first place but until I master that, I will use this technique quite often, I suspect.
With thanks to Adam
