Abstract
A method, system, apparatus, article of manufacture, and computer program product provide the ability to detect junctions. 3D pixel image data is obtained/acquired based on 2D image data and depth data. Within a given window over the 3D pixel image data, for each of the pixels within the window, an equation for a plane passing through the pixel is determined/computed. For all of the determined planes within the given window, an intersection of all of the planes is computed. A spectrum of the intersection/matrix is analyzed. Based on the spectrum, a determination is made if the pixel at the intersection is of 3 or more surfaces, 2 surfaces, or is 1 surface.
