TotalImageBoundaryArea
Measures the total image boundary area of the volume of interest defined in a binary image.
Access to parameter description
For an introduction:
On a 2D image, this measurement is more precisely a perimeter and has dimension 1. On a 3D image, it is a surface area and has dimension 2.
If no mask is provided, it corresponds to the bounding box area of the input image. If a mask is provided, it corresponds to the area of the mask image.

On a 2D image, this measurement is more precisely a perimeter and has dimension 1. On a 3D image, it is a surface area and has dimension 2.
If no mask is provided, it corresponds to the bounding box area of the input image. If a mask is provided, it corresponds to the area of the mask image.
Usage without a mask
- On a 2D image $ TS = 2 \times (gx \times cx + gy \times cy) $
- On a 3D image $ TS = 2 \times (gx \times cx \times gy \times cy + gy \times cy \times gz \times cz + gx \times cx \times gz \times cz) $
- gx, gy and gz represent the image size in pixel coordinates along the X, Y, and Z axes respectively.
- cx, cy and cz represent the image calibration spacing in world coordinates along the X, Y, and Z axes.
Usage with a mask
- On a 2D image $ TS = P(M) $
- On a 3D image $ TS = S(M) $
- $M$ is the binary mask image.
- $P$ is the Crofton Perimeter.
- $S$ is the 3D surface area given by the Area3d algorithm.
