Abstract
Methods and systems for digitally enhancing an initial image of a material to which a plurality of stains were previously applied, that generally comprise: unmixing the image into a plurality of individual reconstructed images, each individual image corresponding to one of the stains; estimating a residual image corresponding to the difference between the original image and the reconstructed images; adjusting one or more components of the individual images; mixing the adjusted components using one or more estimated mixing coefficients; and adding the residual image to the mixed adjusted components to generate an enhanced image.
Claims11
A method for digitally enhancing an initial image of a material to which a plurality of stains were previously applied, comprising the steps of:
- unmixing the initial image into a plurality of individual reconstructed images, wherein the initial image corresponds to an image data set generated from an imaging device, and wherein each individual image corresponds to one of the stains;
- estimating a residual image corresponding to a difference between the initial image and the unmixed reconstructed images;
- adjusting one or more components of the individual reconstructed images, wherein the adjusting is based on a characteristic of the stain;
- mixing the adjusted components;
- and
- adding the residual image to the mixed adjusted components to generate an enhanced image.
A system for digitally enhancing an initial image of a material to which a plurality of stains were previously applied, comprising:
- a memory component for at least temporarily storing the image of the material;
- a processor that unmixes the initial image into a plurality of individual reconstructed images, wherein the initial image corresponds to an image data set generated by an imaging device, and wherein each individual image corresponds to one of the stains;
- estimates a residual image corresponding to a difference between the initial image and the reconstructed images;
- adjusts one or more components of the individual images wherein the adjusting is based on a characteristic of the stain;
- mixes the adjusted components using estimated mixing coefficients;
- and adds the residual image to the mixed adjusted components to generate an enhanced image;
- and
- a display device for displaying the enhanced image.
