I have the following problem:
I need to detect changes between two more or less similar image.
In that case, I want to detect the missing parts.
Lets assume that the displacement is no more that 2px, and there is no significant change in light (but there is some) or camera pose.
What I want as an output, is a binary image about if there is a signifiacant change at that position.
My naive idea was, to apply blur (aroud the size of expected displacement), and compare pixelwisely, but in practice its not working really well. (mainly it has a huge amount of noise around edges)
Any better idea for this problem?
