Figure 2From: Fractal dimension analysis of malignant and benign endobronchial ultrasound nodes Relationship between the log area and the log perimeter of a node image. The slope of the straight line would give us the form in that the log- perimeter grows linearly with the log-area. In this example the relationship agrees with a lineal model. Log(Perimeter[n]) = K + αLog(Area[n]). Coefficients: α = 0.62, K = 2.31.Back to article page
