Stitch together images with exactly matching (pixel to pixel) overlaps

Question

I have a bunch of images in a folder that are effectively just pieces of one image that was broken into overlapping parts. How can I quickly and programmatically recombine these images to create the original image?

I would prefer a solution that uses python or mathematica (or is an existing application), but I am open to other ideas as well (I am fairly proficient with Java).

Answer 1

i realize this answer comes very late, but since i spent some time googling this problem, i thought i would post a fairly simple solution using python.

import cv2
#works in version 4.2
cv2.__version__

#mode=0 photos, mode=1 scans
stitcher = cv2.Stitcher.create(mode=1)

img1 = cv2.imread("frame-0021.png")
img2 = cv2.imread("frame-0022.png")

result = stitcher.stitch((img1, img2))
cv2.imwrite("stitched.png", result[1])
