SPATIALLY VARYING LOG-CHROMATICITY NORMALS FOR USE IN AN IMAGE PROCESS

摘要

In a first exemplary embodiment, an automated, computerized method is provided for processing an image. The method includes the steps of providing an image file depicting an image defined by image locations, in a computer memory, generating a bi-illuminant chromaticity plane in a log color space for representing the image locations of the image in a log-chromaticity representation for the image, providing a set of estimates for an orientation of the bi-illuminant chromaticity plane and calculating a single orientation for each one of the image locations as a function of the set of estimates for an orientation.

1. An automated, computerized method for processing an image, comprising the steps of:
providing an image file depicting an image defined by image locations, in a computer memory; providing a set of estimates for an orientation determined as a function of a bi-illuminant dichromatic reflection model; and calculating a single orientation for each one of the image locations as a function of the set of estimates for the orientation.
