Subject:      Image registration and alignment

Hi all,

I'm trying to register two images using the TurboReg plug-in. As far as I can tell,
the plug-in always returns a 32-bit gray (!) stack of two images. The first image
in the resulting stack is the transformed source image, and the second is a mask
layer, which, on my machines always is white (does anyone know the function of this
mask layer?). The image layer of the stack has higher contrast than the initial
source image.

Is there any way to:
    - return an 8-bit gray image (no stack)?
    - avoid the contrast adjustments done by the plug-in?
    - make the cross-hairs for the adjustment points change with the image
resolution?

I've had a look at the source code, but since I know nothing about JAVA, I couldn't
find the solutions. I managed to change the size of the cross-hairs, but only in a
static way, not dynamically changing with the image size.


One more question, while I'm at it; Is there a plug-in for aligning two or more
overlapping images (not stacks) in a mosaic?  It must preferably work with 24-bit
RGB-images.
(What I need, is something similar to the mosaic function found in PanaVue Image
Assembler, or PanoramaTools with a very long focal lenght setting).

Any help is greatly appreciated!


Best wishes, and thank you for a great program!
