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.
I found the answer . Previously, My approach was not correct, i was first segmenting the image from background then using the open nite for detecting ground plane and removing from the segmented image. It won't work well because the image for which ground was detected is now converted to segmented image. Thus the correct way to firstly detect ground plane using openni of the depth image then remove it. Now , i got the ground separated image.

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.
