Analysis: A Step Toward Standardizing Diabetic Foot Images.

In this issue of Journal of Diabetes Science and Technology Yap and coauthors report on the design and present results from a reliability study of the application called FootSnap that is intended for standardization of the distance and the orientation of the camera relative to the diabetic foot that is photographed. To produce standardized photographs FootSnap uses a straightforward, yet original and useful method. However, other systems have been reported and clinically tested earlier, in which the same parameters of foot images might be standardized and which are free of some limitations of FootSnap. Nevertheless, FootSnap should contribute to increase clarity of documenting changes in the diabetic foot shape, texture color and lesions, and it should facilitate application of automatic image processing algorithms.
