What exactly is a connected componnent in an image?

If all pixels in the set S are connected to all other pixels through a path, then S is a connected component. Thus a connected component is the very intuitive concept of a continuous region of equal-valued pixels.

What is connected components in image?

A connected component is a set of connected pixels that share a specific property, V. Two pixels, p and q, are connected if there is a path from p to q of pixels with property V. A path is an ordered sequence of pixels such that any two adjacent pixels in the sequence are neighbors.

Connected Component Definition

A set of nodes forms a connected component in an undirected graph if any node from the set of nodes can reach any other node by traversing edges. The main point here is reachability. In connected components, all the nodes are always reachable from each other.

What does OpenCV connected components do?

Connected component labeling (also known as connected component analysis, blob extraction, or region labeling) is an algorithmic application of graph theory used to determine the connectivity of “blob”-like regions in a binary image.

What is connectivity in image?

Pixel connectivity defines which other pixels each pixel is connected to. A connected group of foreground pixels in a binary image is called an object or a connected component.
