US 12,295,739 B2 · Measuring and monitoring skin feature colors, form and size

Abstract

Kits, diagnostic systems and methods are provided, which measure the distribution of colors of skin features by comparison to calibrated colors which are co-imaged with the skin feature. The colors on the calibration template (calibrator) are selected to represent the expected range of feature colors under various illumination and capturing conditions. The calibrator may also comprise features with different forms and size for calibrating geometric parameters of the skin features in the captured images. Measurements may be enhanced by monitoring over time changes in the distribution of colors, by measuring two and three dimensional geometrical parameters of the skin feature and by associating the data with medical diagnostic parameters. Thus, simple means for skin diagnosis and monitoring are provided which simplify and improve current dermatologic diagnostic procedures.

Claims21

Dependent claims

A non-transitory computer readable storage medium storing instructions that, when executed by a processor, cause the processor to perform a method for image skin diagnosis, the method comprising:

receiving a group of images of a skin feature next to a calibrator having a plurality of colored areas thereon, wherein the skin feature has multiple segments of differing colors, wherein the plurality of colored areas are selected based on a specific medical condition;
analyzing the colors of the multiple segments of the skin feature and the plurality of colored areas of the calibrator commonly captured on at least one image to determine actual colors of the multiple segments of the skin feature;
and
based on the differing colors of the multiple segments of the skin feature, determining an indication of a medical condition associated with the skin feature.
