Abstract
Techniques for capturing three-dimensional image data of a scene and processing light field image data obtained by an optical wavefront sensor in 3D imaging applications are provided. The disclosed techniques provide a depth map of an observable scene from light field information about an optical wavefront emanating from the scene, and make use of color filters forming a color mosaic defining a primary color and one or more secondary colors, and color radial transfer functions calibrated to provide object distance information from the spatio-spectrally sampled pixel data.
