Black runs (Connected Components Labeling)
Connected components labeling scans an image and groups its pixels into components (black runs) based on pixel connectivity, i.e. all pixels in a connected component share similar pixel intensity values and are in some way connected with each other. Blackrun is a group of connected pixels.
Extracting and labeling of various disjoint and connected components in an image is essential to many automated image analysis applications.
Current implementation of the algorithm uses 4-connected analysis to find the connected components (blackruns).
