Suppose you have multiple photos of the same object (from slightly different angles), each have some obstacles in foreground.

First image with an obstacle Second image with an obstacle

You added an alpha channel to each picture and "erased" the obstacle (leaving "holes" in each picture).

First image with a hole Seconf image with a hole

You want to combine them and obtain a picrure without obstacles or holes.

Resulting image

What [open source] software should I use to do this? I tried ALE, but it does not preserve alpha channels. Will Hugin or some Gimp plugin do this?

Update Tried Hugin, got this:

Resulting hugin image

It looks like what I want, hovewer...

  1. It asks for some "lense" while this is not a photo at all. I tried entering "infinity" as focal length (meaning "don't distort anything"), but it just failed in that mode.
  2. It failed to align the size of images until I manually adjusted the "lens" parameter of one of the images. Can it use control points to scale image in addition to moving?
  3. I don't know how to turn off those "photometrics".

If your example is accurate, simply add the various images as layers in GIMP. The hole in the top layer will show the good image below. The hole in the lower layer doesn't matter if the top layer has good data for that portion.

Order the layers so that the best image is on top and the worst on bottom.

If you have poor quality areas that you want to average out, that's another matter.
