A non-transitory computer readable medium for tracking healing progress of multiple adjacent wounds, the computer readable medium containing instructions that when executed by a processor cause the processor to perform a method, the method comprising: receiving a first image of a plurality of adjacent wounds in proximity to a form of colorized surface having colored reference elements thereon, wherein each wound has multiple segments of differing colors; using the colored reference elements in the first image to determine first colors of the plurality of wounds, wherein during determination of the first colors, the colored reference elements are used to correct for local illumination conditions; receiving a second image of the plurality of wounds in proximity to the form of colorized surface, wherein capture of the second image occurs at least one day after capture of the first image; using the colored reference elements in the second image to determine second colors of the plurality of wounds in the second image, and wherein, during determination of the second colors, the colored reference elements are used to correct for local illumination conditions; matching each of the plurality of wounds in the second image to a corresponding wound of the plurality of wounds in the first image; and determining an indicator of the healing progress for each of the plurality of wounds based on changes between the first image and the second image, wherein matching of the plurality of wounds in the second image to a corresponding wound of the plurality of wounds in the first image comprises: determining a time difference between the first image and the second image; predicting an expected appearance of each of the plurality of wounds in the second image based on the determined time difference; and using the predicted expected appearance for matching each of the plurality of wounds in the second image to the plurality of wounds in the first image. receiving a first image of a plurality of adjacent wounds in proximity to a form of colorized surface having colored reference elements thereon, wherein each wound has multiple segments of differing colors; using the colored reference elements in the first image to determine first colors of the plurality of wounds, wherein during determination of the first colors, the colored reference elements are used to correct for local illumination conditions; receiving a second image of the plurality of wounds in proximity to the form of colorized surface, wherein capture of the second image occurs at least one day after capture of the first image; using the colored reference elements in the second image to determine second colors of the plurality of wounds in the second image, and wherein, during determination of the second colors, the colored reference elements are used to correct for local illumination conditions; matching each of the plurality of wounds in the second image to a corresponding wound of the plurality of wounds in the first image; and determining an indicator of the healing progress for each of the plurality of wounds based on changes between the first image and the second image, wherein matching of the plurality of wounds in the second image to a corresponding wound of the plurality of wounds in the first image comprises: determining a time difference between the first image and the second image; predicting an expected appearance of each of the plurality of wounds in the second image based on the determined time difference; and using the predicted expected appearance for matching each of the plurality of wounds in the second image to the plurality of wounds in the first image. determining a time difference between the first image and the second image; predicting an expected appearance of each of the plurality of wounds in the second image based on the determined time difference; and using the predicted expected appearance for matching each of the plurality of wounds in the second image to the plurality of wounds in the first image.
