connected components algorithm
What is a connected component in a graph?
A connected component is a set of vertices in a graph that are connected to each other. A graph can have multiple connected components. Inside a component, each vertex is reachable from every other vertex in that component. There are several algorithms to identify Connected Components in a graph. The most popular ones are:
What is an example of a connected component?
For example in the graph shown below, {0, 1, 2} form a connected component and {3, 4} form another connected component. A connected component is a set of vertices in a graph that are connected to each other. A graph can have multiple connected components. Inside a component, each vertex is reachable from every other vertex in that component.
How does a connected component algorithm work?
This algorithm computes connected components for a given graph. Connected components are the set of its connected subgraphs. Two nodes belong to the same connected component when there exists a path (without considering the direction of the edges) between them. Therefore, the algorithm does not consider the direction of edges.
What is connected component labeling in MATLAB?
Matlab also has a built-in function to do connected component labeling. This is a computer vision algorithm to detect and count the number of connected regions — also called blobs — in a binary image. Often, this is done after a segmentation algorithm. The resulting…
