How robust is the SVM wound segmentation?

This paper investigates the robustness of automatic wound segmentation. The work builds upon an automatic segmentation procedure by the Support Vector Machine (SVM) - classifier presented in [8], [9]. Here we extend the procedure by incorporating textural features and the deformable snake adjustment to refine SVM-generated wound boundary. The robustness of SVM-based segmentation is tested against different feature spaces using a long sample of training images featuring a broad variety of wounds' appearance. Recommendations drawn from these experiments provide a useful guideline for the development of a software support system for the visual monitoring of chronic wounds in wound care units.
