A method of displaying data representative of a feature on a skin surface of a patient, the method comprising:

• receiving a first data set captured at a first time;
• receiving a second data set captured at a second time;
• in each of the first data set and the second data set—
• determining a boundary of the feature;
• identifying a plurality of sub-regions within the boundary;
• and
• identifying one or more tissue types in each sub-region;
• displaying a first representation of the feature based on the first data set, wherein the first representation includes the feature, the boundary of the feature determined in the first data set, the sub-regions within the boundary identified in the first data set, and the one or more tissue types in each sub-region identified in the first data set;
• and
• displaying a second representation of the feature based on the second data set, wherein the second representation includes the feature, the boundary of the feature determined in the second data set, the sub-regions within the boundary identified in the second data set, and the one or more tissue types in each sub-region identified in the second data set.
