Dear list,
I want to multiply two images but without the same x and y origin. I use the calibration method but it seem that x and y origin are not taken into account. I put a figure in attach file. Is there a possibility to do it with imageJ ?

You can resize the canvas so the 2nd image is offset to the 1st one (or viceversa) and fill the offset space with 1 so when multiplied, the result is unchanged. G. |
Hi,
I want to program this. Do you have an example ? Thanks.

... or simply re-sample one image, shifting the images so that they
formally overlap (lots of ImageJ examples out there; try my trivial Shift_Image plugin if the rotation and scale doesn't have to be corrected for: http://www.astro.physik.uni-goettingen.de/~hessman/ ImageJ/Astronomy/).

Or something like this: run("Clown (14K)"); run("8-bit"); run("Duplicate...", "title=clown-1.jpg"); run("Select All"); run("Fill"); run("Subtract...", "value=254"); setPasteMode("Copy"); selectWindow("clown.jpg"); run("Copy"); selectWindow("clown-1.jpg"); run("Select None"); makeRectangle(98, 41, 320, 200); run("Paste"); run("Select None"); imageCalculator("Multiply create", "clown.jpg","clown-1.jpg"); Cheers, G. |

The turboreg plugin from http://bigwww.epfl.ch/thevenaz/turboreg/ might
be helpful,too. Karl-Heinz Karl-Heinz Kunzelmann |
