abstract = "Planes are important geometric features and can be used in a wide
range of vision tasks like scene reconstruc- tion, path planning
and robot navigation. This work aims to illustrate a plane
segmentation system based on homography computation and optical
flow estimation. Firstly, using two image frames from a monocular
sequence, a set of match pairs of interest points is obtained. An
algorithm was developed to cluster interest points belonging to
the same plane based on the reprojection error of the affine
homography. From the calculated homographies, the planar flow is
computed for each image pixel. Following this, the estimated
optical flow is used to expand and identify each detected plane.
An optical flow estimation method based on color information is
presented. Tests were performed in different sequences of indoor
and outdoor images and results validate the proposed system.",
