General Description

The ImageJ Shape Filter Plugin uses the [ij-blob] library to filter objects in binary scenes by its shape.

Shape Filter Plugin (ImageJ/Fiji)

Development status	active

Area ( $A$ ): The area enclosed by the outer contour of an object.
Area Convex Hull ( $C$ ): The area enclosed by the convex hull of the outer contour of an object.
Perimeter ( $P$ ): The perimeter of the outer contour of an object.
Perimeter Convex Hull ( $H$ ): The perimeter of the convex hull of the particle.
Feret Diameter: The maximum distance between the two parallel tangents touching the particle outline in all directions.
Min. Feret Diameter: the minimum distance between the two parallel tangents touching the particle outline in all directions.
Long Side Minimum Bounding Rectangle: The larger side of the minimum bounding rectangle.
Short Side Minimum Bounding Rectangle: The smaller side of the minimum bounding rectangle.
Aspect Ratio: Defined as $L/S$
Area to Perimeter Ratio: Defined as $A/P$
Circularity: Defined as $P^{2}/A$
Elongation: Defined as $1 - S/L$
Convexity: Defined as $H/P$
Solidity: Defined as $A/C$
Number of Holes: The number of holes inside an object.
Thinnes Ratio: Inverse proportional to the circularity. Furthermore it normed. It is defined as $4\pi A/P^{2}$
Contour Temperatur: It has a strong relationship to the fractal dimension, defined as $\left(log_{2}\left(\frac{2P}{P-H}\right)\right)^{-1}$
Fractal Box Dimension: Estimated fractal dimension by the box count algorithm. The default box-sizes are “2,3,4,6,8,12,16,32,64”.
