 Ten real-valued features are computed for each cell nucleus:
 
 a) radius (mean of distances from center to points on the perimeter)
+
 b) texture (standard deviation of gray-scale values)
+
 c) perimeter
+
 d) area
+
 e) smoothness (local variation in radius lengths)
+
 f) compactness (perimeter^2 / area - 1.0)
+
 g) concavity (severity of concave portions of the contour)
+
 h) concave points (number of concave portions of the contour)
+
 i) symmetry
+
 j) fractal dimension ("coastline approximation" - 1)
