image labeling algorithm by steve

i have read tutorial about image labeling by Steve

,i decide to implement this algorithm that he explained here by Steve http://blogs.mathworks.com/steve/2007/06/12/connected-component-labeling-part-7/

i just need to know how to connect each runs

if i have starting index and run length of each runs

how to now that run1 connect with run2 and give lable to them

and so on ....

plase any help

What's wrong with bwlabel or bwconncomp?

doc bwlabel

more explain please as i want to implment by code rather than by function

the matlab help say

Run-length encode the input image.

Scan the runs, assigning preliminary labels and recording label equivalences in a local equivalence table.

Resolve the equivalence classes.

Relabel the runs based on the resolved equivalence classes.

can any give to us simple example to understand the algorithem??
