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.

Abstract translation: 一种图像处理系统和方法，用于从由场景的多个2D视图，特别是场景中的对象的均匀表面重构的3D图像信息中平滑不规则。 该方法定义了与场景的多个2D图像视图中的一个的多个像素重叠的窗口。 每个像素与预定义的3D深度信息相关联，并且还与匹配曲线相关联。 被摄体像素位于与窗口重叠的多个像素内。 该方法计算与窗口重叠的多个像素相关联的平均3D深度信息，并且如果所计算出的平均3D深度信息在所述主题像素的误差区域内，则将所计算的平均3D深度信息分配给所述主题像素的3D深度信息 与对象像素相关联的匹配曲线。
