1. A computer-implemented method comprising:
receiving an image comprising a plurality of image points;
constructing a first plane in the image based on a first subset of the plurality of image points that belong to the first plane;
identifying a second subset of the plurality of image points that belong to the first plane and are not part of the first subset of image points;
removing the first subset of image points and the second subset of image points from the plurality of image points, wherein removing produces a remaining subset of the plurality of image points in the image; and
annotating the remaining subset of image points.
