Drone image compare including sift registration,shadow detection, plant detection and a optimized image difference
Firstly, we load 2 images and begin to do registration
First day
Second day
Registration(the second day image does warpaffine)
Then we detect shadow area(they are low confidence area so we decide to give it up.An efficent and real time shadow removal is quite hard for me)
Also we are not intersted in green plants so we also detect green plants in an image
finally we have the changing area with the removal of the above masks. I will really appreciate someone can tell me how to remove those roads, because they are not changed at all.
