Abstract
An apparatus and method for filtering depth information received from a capture device. Depth information is filtered by using confidence information provided with the depth information based an adaptively created, optimal spatial filter on a per pixel basis. Input data including depth information is received on a scene. The depth information comprises a plurality of pixels, each pixel including a depth value and a confidence value. A confidence weight normalized filter for each pixel in the depth information is generated. The weight normalized filter is combined with the input data to provide filtered data to an application.
