Abstract

Growth factor effects on blood vessel patterns were assessed with a fast and automated method that measures complexity (extended counting method: XCM; Sandau, 1996). XCM is a robust estimator of complexity not only in theory but also in practice: 1) it fulfills the quasi-maximum-property; 2) it shows reduced variance due to pattem translation and rotation; 3) it is less sensitive to image manipulations and thresholding. XCM is superior to traditional fractal analysis for detecting changes in vascular complexity following growth factor and control treatment.
