Area | Total area of region. This feature can be computed by RegionArea. |
BoundingBoxBottom | Bottom position of region bounding box. Bounding box of a region can by obtained by RegionBoundingBox. |
BoundingBoxHeight | Height of region bounding box. Bounding box of a region can by obtained by RegionBoundingBox. |
BoundingBoxLeft | Left position of region bounding box. Bounding box of a region can by obtained by RegionBoundingBox. |
BoundingBoxRight | Right position of region bounding box. Bounding box of a region can by obtained by RegionBoundingBox. |
BoundingBoxTop | Top position of region bounding box. Bounding box of a region can by obtained by RegionBoundingBox. |
BoundingBoxWidth | Width of region bounding box. Bounding box of a region can by obtained by RegionBoundingBox. |
Circularity_BoundingCirclePreserving | Ratio of region area to area of its minimal bounding circle. This feature can by calculated by RegionCircularity. |
Circularity_PerimeterPreserving | Ratio of region area to area of circular region with the same perimeter as in source region. This feature can by calculated by RegionCircularity. |
Circularity_RadiusPreserving | Ratio of region area to area of circular region with the same radius as in source region. This feature can by calculated by RegionCircularity. |
Convexity | Ratio of region area to area of its convex hull. For details, see RegionConvexity. |
DiameterLength | Length of region diameter. Read more: RegionDiameter. |
Elongation | Ratio of region length to its width. For details, see RegionElongation. |
MajorAxisLength | Length of the region major elliptic axis. Region axes can be determined by RegionEllipticAxes. |
MassCenterX | OX coordinate of region mass center. Mass center of a region can be calculated by RegionMassCenter. |
MassCenterY | OY coordinate of region mass center. Mass center of a region can be calculated by RegionMassCenter. |
MinorAxisLength | Length of the region minor elliptic axis. Region axes can be determined by RegionEllipticAxes. |
NumberOfHoles_EightDirections | Number of region holes computed using EightDirections connectivity by RegionNumberOfHoles. |
NumberOfHoles_FourDirections | Number of region holes computed using FourDirections connectivity by RegionNumberOfHoles. |
