Abstract
Methods and apparatus for image processing include performing visual sub-band decomposition of an image using human visual system characteristics to generate a plurality of sub-band decomposed images, independently processing the plurality of sub-band decomposed images with at least one application, and fusing the independently processed sub-band decomposed images to reconstruct an output image.
Claims19
A computer-implemented method, comprising:
- performing visual sub-band decomposition of an image using human visual system characteristics to generate a plurality of sub-band decomposed images based on a minimum difference between pixel intensities in the image for the human visual system to register a difference;
- independently processing the plurality of sub-band decomposed images with at least one application on a computer;
- and
- fusing the independently processed sub-band decomposed images to reconstruct an output image.

An article, comprising:
- a non-transitory machine-readable medium that stores executable instructions to enable a computer perform the steps of:
- performing visual sub-band decomposition of an image using human visual system characteristics to generate a plurality of sub-band decomposed images based on a minimum difference between pixel intensities in the image for the human visual system to register a difference;
- independently processing the plurality of sub-band decomposed images with at least one application on a computer;
- and
- fusing the independently processed sub-band decomposed images to reconstruct an output image.

A system, comprising:
- a first decomposition module to decompose an image into a first sub-band based on human visual system characteristics;
- a second decomposition module to decompose the image into a second sub-band based on human visual system characteristics based on a minimum difference between pixel intensities in the image for the human visual system to register a difference;
- a third decomposition module to decompose the image into a third sub-band based on human visual system characteristics;
- a processing module to process the decomposed images from the first, second, and third sub-band modules;
- and
- a fusion module to fuse the processed decomposed images from the processing module.
