draw or delete pixels of images in a stack

aget
Hi, could anyone give advice about editing images, like deleting some areas, or draw something, in an image 3D stack? i want to manually clean some unrelated noise in it and make a better 3D. Thanks.

Re: draw or delete pixels of images in a stack

Hi,

A nice way for doing that is to use 3Dviewer :

select your stack in the 3dviewer
get the right orientation
select the freehand selection tool
draw the part you want to remove
use "fill selection" in 3dviewer

manually align two RGB images?

Kenneth Sloan-2
In reply to this post by aget
I need to manually align (no - auto alignment won't work) THREE images (A,B,C).  Aligning B to A, and then aligning C to A,
will work just fine (in version 2 I might want to align both B and C to A at the same time…but, one step at a time).

My plan is to display A and B and provide controls to: a) move/rotate B and b) use a slider to cross fade between A and B to check the alignment.

When done, all I want (for now) is to write out a 3x3 matrix representing the transformation to apply to B to align it with A.

[I may eventually want to deal with non-rigid-body transformations…but later, much later]

So - who has a plugin that does this, or something like it, or something else that uses the same basic tools (move an image around wrt a second image, crossfade slider).

I'll be in Mondorf Wednesday-Sunday.  I hereby offer a beer to the best response!

I'm on the road (mostly in the air) starting tomorrow (Friday) - but I'll be reading e-mail and here.

Hi Ken,

have you tried TrakEM2?  It's in Fiji and here is a nice screencast for
how to do manual alignment:

You can get the affine matrix through Fiji's Beanshell interpreter.
Select the aligned image and execute:

Display.getFront().getActive().getAffineTransform();

Best,
Stephan
