Abstract
A method and system for processing images to, for example, capture artwork includes capturing a target image and an image of a reference. The reflectance functions of the target image are then measured. The target image is processed, using the measured reflectance functions and the captured image of the reference, to calculate a correction transform associated with the captured target image.
Claims21
A method for processing images comprising the steps of:
- capturing a target image;
- capturing an image of a reference;
- measuring reflectance functions of said target image;
- and
- processing said captured target image, based on said measured reflectance functions and said captured image of said reference, to calculate a correction transform associated with said captured target image.
An image processing system comprising:
- an image capture device for capturing a target image and a reference;
- and
- a processor for processing said captured target image, based on measured reflectance functions of said target image and said captured image of said reference, to calculate a correction transform associated with said captured target image.
A computer-readable medium, containing data for reproducing a plurality of images, comprising:
- a plurality of data structures, each associated with one of said plurality of images, each data structure including:
- a set of pixel values associated with an image;
- and
- a corresponding correction transform associated with said image
- wherein a corresponding correction transform associated with a first one of said plurality of images is different than a corresponding correction transform associated with a second one of said plurality of images.
A system for processing images comprising the steps of:
- means for capturing a target image;
- means for capturing an image of a reference;
- means for measuring reflectance functions of said target image;
- and
- means for processing said captured target image, based on said measured reflectance functions and said captured image of said reference, to calculate a correction transform associated with said captured target image.
