| description | Background
Although measuring would size using digital photography is a quick and simple method to evaluate the skin wound, the possible compatibility of it has not been fully validated.
Purpose
To investigate the error rate of our newly developed wound surface area calculation using digital photography.
Methods
Using a smartphone and a digital single lens reflex (DSLR) camera, four photographs of various sized wounds (diameter: 0.5‐3.5 cm) were taken from the facial skin model in company with color patches. The quantitative values of wound areas were automatically calculated. The relative error (RE) of this method with regard to wound sizes and types of camera was analyzed.
Results
RE of individual calculated area was from 0.0329% (DSLR, diameter 1.0 cm) to 23.7166% (smartphone, diameter 2.0 cm). In spite of the correction of lens curvature, smartphone has significantly higher error rate than DSLR camera (3.9431±2.9772 vs 8.1303±4.8236). However, in cases of wound diameter below than 3 cm, REs of average values of four photographs were below than 5%. In addition, there was no difference in the average value of wound area taken by smartphone and DSLR camera in those cases.
Conclusion
For the follow‐up of small skin defect (diameter: |

Conclusion
For the follow‐up of small skin defect (diameter: <3 cm), our newly developed automated wound area calculation method is able to be applied to the plenty of photographs, and the average values of them are a relatively useful index of wound healing with acceptable error rate.</description><identifier>ISSN: 0909-752X</identifier><identifier>EISSN: 1600-0846</identifier><identifier>DOI: 10.1111/srt.12398</identifier><identifier>PMID: 28718523</identifier><language>eng</language><publisher>England: John Wiley & Sons, Inc</publisher><subject>Algorithms ; Automation ; Cameras ; Curvature ; Digital photography ; Error analysis ; Error correction ; Facial Injuries - pathology ; Facial Injuries - physiopathology ; Humans ; image analysis ; Photography ; Photography - instrumentation ; Photography - methods ; Single lens reflex ; Skin ; Skin - injuries ; Skin - pathology ; Smartphone ; Smartphones ; Surface area ; Wound Healing ; wounds and Injuries</subject><ispartof>Skin research and technology, 2018-02, Vol.24 (1), p.117-122</ispartof><rights>2017 John Wiley & Sons A/S.
