Abstract
An image processing system and method for smoothing irregularities from 3D image information that was reconstructed from a plurality of 2D views of a scene, and particularly from homogeneous surfaces of objects in a scene. The method defines a window that overlaps a plurality of pixels of one of a plurality of 2D image views of a scene. Each pixel is associated with predefined 3D depth information, and further is associated with a matching curve. A subject pixel is located within the plurality of pixels overlapped by the window. The method calculates an average 3D depth information associated with the plurality of pixels overlapped by the window, and assigns the calculated average 3D depth information to the 3D depth information of the subject pixel, if the calculated average 3D depth information is within an error region of a matching curve associated with the subject pixel.
