Disconnectedness: A new moment invariant for multi-component shapes

作者：

Highlights：

• Disconnectedness: A New Moment Invariant for Multi-Component Shapes is introduced;

• The measure expresses numerically how much shape commponents are disconnected;

• The measure is rotation, scaling and translation invariant;

• The new measure is based on the shape moments computation and is fast to compute;

• The new measure is a generic one, applicable in a wide spectrum of applications.
