What if I want to assign a number in index for each of the cells even if they are very close to each other? The only distinction is the boundary of each cell separating them and shape is quite variable for each of the cells? Thanks Hi Steve,

I need to get this information from websites, books, or anywhere else where there is a recognition by the scientific community. Yes it’s seriously.

The first link I see when I Google for "connected component labeling" is for a lengthy Wikipedia article with detailed descriptions of several algorithms, a number of diagrams, relevant cross references, and external reference links.

Thanks.

I think you can use some basic Internet searches to find a lot of information about them. Domenico—These are pretty widely used terms.
