General Description

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

Shape Features

  • 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”.
