IntensityIntegral3d
Computes the sum of all voxel intensities of a three-dimensional image.
Access to parameter description
For an introduction: section Image Analysis.
In the continuous case, the 3D intensity integral is defined as:
$$ V(X)=\int_{R^3}I(x,y,z)dxdydz $$
In the discrete case, Intensity Integral is approximated by the sum of the pixel intensities in X: $$ V(X)=\sum_{i,j,k}I(x_i,y_j,z_k) $$
Where $I(x_i,y_j,z_k)$ = the intensity of voxel of coordinates $x_i,y_j,z_k$
On a grayscale image, this algorithm computes the sum of gray values in the image.
This algorithm takes into account the pixel size given by the input image calibration property. Each pixel intensity is multiplied by the pixel size in the X and Y directions before being added to the result.
On a binary image it amounts to compute a 3D volume.
