Eq Diameter

EqDiameter_{2D} = \frac{4 \cdot Area}{π}

EqDiameter_{3D} = 3 \frac{6 \cdot Volume}{π}

Fill Area

Incircle Diameter

Length

Length = \frac{Perimeter + Perimeter ^{2} - 16 \cdot Area}{4}

Line Length

Max Feret

Max Feret 90

Min Feret

Min Rect Area

Object Pixel/Voxel Count

Object Area/Volume

Outer Perimeter

Perimeter

Perimeter = \frac{π \cdot ( P _{0} + P _{45} + P _{90} + P _{135} )}{4}

Surface

Perimeter Contour

Volume Eq Cylinder

VolumeEqCylinder = \frac{( π \cdot d ^{2} ) ( l - d )}{4} + \frac{π \cdot d ^{3}}{6}

l = max (MaxFeret, Length)

d = min (MinFeret, Width)

Volume Eq Sphere

VolumeEqSphere = \frac{π \cdot EqDiameter ^{3}}{6}

Width

Width = \frac{Area}{Length}
