US 2026/0301228 A1 · METHOD FOR COLOR CORRECTION BASED ON GROUND TRUTH COLOR CHART

Abstract

A method for correcting colors in a captured image, which includes receiving a ground truth color chart having a plurality of reference color patches, capturing an image based on a first color domain from a scene or sample of interest juxtaposed with the ground truth color chart, obtaining ground truth color values associated with each of the reference color patches in a second color domain, generating a scene or sample-specific dataset using the plurality of color values of the reference color patches in the ground truth color chart in the first and second color domains as the input and output, training a neural network of color correction with the dataset, and applying the trained neural network to convert portion of the scene or sample of interest outside the ground truth color chart in the first color domain to thereby generate an output image based on the second color domain.

Dependent claims

A method for correcting colors in a captured image, comprising:

receiving a ground truth color chart having a plurality of reference color patches;
capturing an image based on a first color domain from a scene or sample of interest juxtaposed with the received ground truth color chart, the captured image thereby including the plurality of reference color patches;
obtaining ground truth color values associated with each of the reference color patches in a second color domain;
generating a scene or sample-specific dataset using the plurality of color values of the reference color patches in the ground truth color chart in the first color domain and the second color domain as the input and output, respectively;
training a neural network of color correction with the scene or sample-specific dataset;
and
applying the trained neural network to convert portion of the scene or sample of interest outside the ground truth color chart in the captured image in the first color domain to thereby generate an output image based on the second color domain.

4 more elements

A method of determining concentration of a molecule in a sample from a captured image, comprising:

establishing a color-corrected image (output image) from a captured image from a scene or sample of interest, the output image provides color corrections from a first color domain to a second color domain, the established output image associated with color values of the sample in the second color domain;
and
using color values of the output image of the sample in the second color domain to determine the concentration of a molecule of interest.
