These algorithms process an image in the raster-scan order (top to bottom, left to right) at least twice.
Weblabel (usually the smallest one of the component). They differ on three points: the mask topology, the number of tests for a given mask to find out the label, and the equivalence management algorithm. Using Rosenfeld mask (fig. 1), only two basic patterns trig-ger label creation (fig. 2), whatever is the connectivity (here 8-connectivity). WebSep 1, 2005 · We propose two new methods to label connected components based on iterative recursion: one directly labels an original binary image while the other labels the boundary voxels followed by one-pass labelling of non-boundary object voxels.The novelty of the proposed methods is a fast labelling of large datasets without stack overflow and a …
