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 agroup of connected pixels. 

Extracting and labeling of various disjoint and connected components in an image is central to many automated image analysis applications.
