Block diagram for measurement of wound sizes.
To measure the size of wound precisely, pre-processing steps are needed before segmentation.
Fig 2.
Wound image analysis using a color patch method.
The area which shows different color and texture compared to around normal skin area was automatically defined as a skin wound using the devised software tool.
