Apr 01, 2014 · Either way, it's trivial with labeling and difficult and faulty with kmeans. If you look at the x,y locations of the points then the centroid of the circle is really close to the centroids of the polygons and the polygon pixels go very near the centroid of the circle and might be classified as circle instead of polygons.
AREA Area of a planar polygon. centroid: CENTROID Center of mass of a polygon. color_list colordot: COLORDOT - plots dots using colormap colordot3: COLORDOT3 - plots dots using colormap complex_demodulate: COMPLEX_DEMODULATE - complex demodulation using a low pass filter. contour_vector: CONTOUR_VECTOR - makes a contour plot of vector data density Firstly we find the centroid of each polygon. For each polygon we apply “centroid” command in the Input Bar. In algebra window are displayed the areas of the polygons: Poly 1 = 1.5, poly 2 = 5, poly 3 = 4, poly 4 = 3, poly 5 = 4.5 and their respective centroids: R=(1,1), S=(8.5,1.5), T=(10.33,8.67), U=(1.67,9.33) and V=(3.56,6.67). meshFacePolygons - Returns the set of polygons that constitutes a mesh faceCentroids - Compute centroids of a mesh faces faceNormal - Compute normal vector of faces in a 3D mesh vertexNormal - Compute normals to a mesh vertices Measures on meshes
