You can do that by first running align_image_stack with the extra option -p test.pto. To deal with this problem it's best to use Hugin to add control points to pairs of images that are removed far away from each other in the stack. So, when image 100 is aligned with image 99, you can bet that it won't be well aligned with image 1. There will be a random walk away from perfect alignment with the first image. When you have more than a few images, the alignment will start to drift, as the remapping is only accurate to within some tolerance. Another potential problem is that the alignment is done in the specified order, and control points are only added to pairs of images that are neighbors in the stack. You can crop them to have maximum overlap using the -C option.įor a large number of input images, you don't want to let align_image_stack find the optimal cropping using the -C option, as the computation will take long. Due to the remapping, the aligned output files won't have perfect overlap anymore. You can change the number of subdivisions using the -g option. The -c 20 option specifies the number of control points in each of the 5 by 5 subdivisions of the pictures to be 20 the default value is 8. The -t 0.3 specifies the maximum misalignment to be 0.3 pixels the default value is 3 pixels (in your case you may need to choose a larger value, e.g. Here the -a al option specifies the prefix of the output files as "al" the aligned images will then be al0000.tif, al0001.tif, etc. You then open a command prompt and type the command: align_image_stack -a al -t 0.3 -c 20 im1.tif im2.tif im3.tif. To align images, you can copy the align_image_stack.exe file to some directory where you put your images im1.tif, im2.tif, etc. A better way to align images is by using the align_image_stack program, which is part of the free of charge Hugin panorama stitcher program.
