Object shape features

Circularity = \frac{4 π \cdot Area}{Perimeter ^{2}}

Convexity = \frac{Area}{ConvexHullArea}

Elongation = \frac{MaxFeret}{MinFeret}

FillRatio = \frac{Area}{FillArea}

MeanChord = \frac{4 \cdot Area}{P _{0} + P _{45} + P _{90} + P _{135}}

Roughness = \frac{ConvexHullPerimeter}{Perimeter}

RoughnessInf = \frac{1}{Roughness}
