Method and Apparatus for Adaptive Exposure Bracketing, Segmentation and Scene Organization

摘要

A method, system and computer program are provided that present a real-time approach to Chromaticity maximization to be used in image segmentation. The ambient illuminant in a scene may be first approximated. The input image may then be preprocessed to remove the impact of the illuminant, and approximate an ambient white light source instead. The resultant image is then choma-maximized. The result is an adaptive Chromaticity maximization algorithm capable of adapting to a wide dynamic range of illuminations. A segmentation algorithm is put in place as well that takes advantage of such an approach. This approach also has applications in HDR photography and real-time HDR video.

1. A method for imaging a scene comprising the steps of:
determining a camera response function based upon one or more images captured with a camera; maximizing chroma in an image in accordance with at least the determined camera response function and one or more perceptual parameters resulting in color consistency; and imaging the scene at an exposure resulting in the maximized chroma.
