Clean a logical segmentation support mask — clean_segmentation

Optionally applies binary close/open morphology and removes small connected components from a 2-D support mask.

Usage

clean_segmentation_mask(
  mask,
  min_mask_area = 1L,
  close_size = 1L,
  open_size = 1L,
  keep_largest = FALSE,
  connectivity = c(8L, 4L)
)

mask: Logical or numeric matrix. Positive/TRUE finite pixels are kept.
min_mask_area: Minimum connected-component area to retain.
close_size: Size of the optional binary closing brush. Use 1 to skip.
open_size: Size of the optional binary opening brush. Use 1 to skip.
keep_largest: Logical; keep only the largest connected component after area filtering.
connectivity: Pixel connectivity for component labeling. Use 8 for diagonal connectivity or 4 for edge-only connectivity.

A logical matrix with the same dimensions as mask.
