replaces small connected components in a binary image image with background pixels.
replaces positive integers in a label matrix m with 0 if their tally is small.
replaces components consisting of n or fewer elements.
Details and Options
- DeleteSmallComponents works with arbitrary 2D and 3D images or label matrices.
- The following options can be given:
CornerNeighbors True whether to include corner neighbors Method Automatic method to determine a size threshold
- Possible settings for the Method option include:
"Cluster" cluster variance maximization (Otsu's algorithm) "Mean" use the mean of component sizes as the threshold "Median" use the median of component sizes as the threshold
- The default setting is Method->"Cluster", corresponding to cluster variance maximization.
