General Description
The ImageJ Shape Filter Plugin use the [ij-blob] library to characterize and filter objects in binary scenes by its shape. Therefore, several features are calculated as shown below.

Shape Features
- Area (): The area enclosed by the outer contour of an object.
- Area Convex Hull (): The area enclosed by the convex hull of the outer contour of an object.
- Perimeter (): The perimeter of the outer contour of an object.
- Perimeter Convex Hull (): 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.
- Max. Inscr. Circle Diameter: The diameter of the maximum inscribed circle.
- Area eq. circle diameter: Equivalent circle diameter
- 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
