Abstract
This method for qualitatively evaluating human livers comprises: a step (301) of computing normalized histograms of colour channels from a portion of a photograph of a liver; a step (304) of loading coefficients obtained at the end of a training phase; a step (305) of extracting from the histograms values corresponding to variables retained at the end of the training phase; a step (306) of computing a linear combination of the extracted values weighted with the loaded coefficients; and a step (308, 309) of displaying information representative of the result of the computation of the linear combination.
Claims20
A device for qualitatively evaluating human livers, comprising:
- a camera for capturing an image of a liver, with the liver being in the donor's body, already removed, or placed in a hypothermic, normothermic and/or subnormothermic graft perfusion machine, when the image is captured;
- an image processor configured to extract at least one portion of the liver's image from the captured image;
- and
- an estimator for estimating the health of the liver, based on the extracted image;
- wherein the estimator is configured to apply the results of training about the characteristics of the image comprising color values measured in the image extracted to assign a quality evaluation to the liver represented by the captured image.
