Khoros implementation of edge focusing system for skin lesion analysis

Many of the important diagnostic indicators used in the clinical assessment of malignancy in melanoma are related to the size and shape of the skin lesion´s outline. As a first stage in the development of a image based diagnosis support package, a system which can deduce an accurate boundary has been created. The further development of this package requires that the boundary location system be made easily accessible for its development, improvement and evaluation. This paper describes the process and results of porting the boundary location system into a highly modular and more intuitively accessible form within the Khoros II image processing environment. The entire process is decomposed and presented in a highly visual manner with the basic processing actions linked by data flow lines, This presentation is ideal for experimentation since elements can be readily exchanged, allowing for simple evaluation of alternatives and for reuse of elements in future projects
