LabelCountByRegion
Computes, for each region of a first label image, the number of objects contained in a second label image.
Access to parameter description
This algorithm can be used, for instance, to compute the number of markers contained in each cell of a life science image, or the number of inclusions in each phase of a material science image.
If the region image is a binary image, it is considered as a single region and the algorithm amounts to computing the number of objects masked by this image.
If the region image is a label image, the number of objects is given for each label of the region image.
