Finding The Connected Components In An Image

1999-9-20Finding the connected components in an 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. An example of an ...
