Image Completion Optimised for Realistic Simulations of Wound Development

Treatment costs for chronic wound healing disturbances have a strong impact on the health care system. In order to motivate patients and thus reduce treatment times there was the need to visualize possible wound developments based on the current situation of the affected body part. Known disease patterns were used to build a model for simulating the healing as well as the worsening process. The key point for the construction of possible wound stages was the creation of a nicely fitting texture including all representative tissue types. Since wounds are mostly circularly shaped, as first step of the healing an image completion based on radial texture synthesis of small patches from the healthy tissue surrounding the wound was developed. The radial information of the wound border was used to optimize the overlap between individual patches. In a similar way complete layers of all other appearing tissue types were constructed and superimposed using masks representing trained possible appearances. Results show that the developed texture synthesis together with the trained knowledge is perfectly suited to construct realistic wound images for different stages of the disease.
