How to programatically create a similar effect to this:

enter image description here

I saw this answer from here: Android Photography App Double Exposure But it is so basic and there is no explanation how it should work; maybe OpenCv would have a better result? Does anyone have any idea on how to implement that?

  • The answer given in the post you linked seems good. Try to load 2 images (same size) as `Mat` objects and then add them with `Core.add`. – Pierre C. Jan 24 '17 at 15:56
  • Can you share the two input images as well ? – ZdaR Jan 24 '17 at 19:24
  • it is just the first image in google for double exposure; I am looking to get at least a similar effect, just did not have any idea where to start, and no documentation on that even in opencv – Filip Luchianenco Jan 25 '17 at 19:17

It looks like one image is thresholded (woman) and used as a mask for second image (lake and trees). Then both images can be added with some weights. You could start with both weights = 0.5 and then play around with them.
