Identify Disjoint Sets of Connected Components

Share:

Description

Identify disjoint sets of contiguous events in a binary field. In many areas of research, this function finds connected components.

Usage

1
disjointer(x, method = "C")

Arguments

x

A numeric matrix or other object that as.im from package spatstat works on.

method

Same argument as that in connected from package spatstat.

Details

disjointer essentially follows the help file for connected to produce a list object where each component is an image describing one set of connected components (or blobs). It is essentially a wrapper function to connected. This function is mainly used internally by FeatureFinder and similar, but could be of use outside such functions.

Value

An unnamed list object where each component is an image describing one set of connected components (or blobs).
