Web22 de fev. de 2024 · 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. We often use connected component analysis in the same situations that contours are used; however, … WebIt also generates a whole hierarchy, with levels that aren't limited to one or two. Each contour can have its own hierarchy, which is determined by the level it is on and the parent-child relationship it has. References.
