Removing the floor in an image .
I I am trying to remove the floor portions present in an image. I am doing programming in C++ using opencv and openni . I had gort he x,y,z coordinates and normal using openni . Can you suggest how to remove the floor portions? background portion is removed . now some portions of ground are still present in the image .I want to remove that.
do you mean "background removal" ?
I have already removed the background but still ground floor portions are present in the image. So an algorithms to remove ground floor would be appreciated.
