Grading Corneal Fluorescein Staining |
摘要 |
The technology described in this document can be embodied in systems and computer-implemented methods for determining a score representing an amount of staining of the cornea. The methods include obtaining a digital image of the cornea stained with a tracer material, receiving a selection of a portion of the image, and processing, by a processing device, the selection to exclude areas with one or more artifacts to define an evaluation area. For each of a plurality of pixels within the evaluation area, a plurality of Cartesian color components are determined and a hue value in a polar coordinate based color space is calculated from the components. An amount of staining of the cornea is then determined as a function of the hue value. The methods also include assigning a score to the evaluation area based on the amount of staining calculated for the plurality of pixels. |

1. A computer-implemented method for determining a score representing an amount of staining of the cornea, the method comprising:
obtaining a digital image of the cornea stained with a tracer material; receiving a selection of a portion of the image; processing, by a processing device, the selection to exclude areas with one or more artifacts to define an evaluation area; for each of a plurality of pixels within the evaluation area:
determining a plurality of color components that are based on a Cartesian color space,determining, from the color components, a hue value in a polar coordinate based color space, anddetermining an amount of staining of the cornea as a function of the hue value; and assigning a score to the evaluation area based on the amount of staining calculated for the plurality of pixels. |
