Not enough information. The end of a labelled area does not necessarily represent a white to black transition: it could represent a transition from any non-black color to black.

What is the rlsa algorithm? For black-white transitions, have you considered the gray level cooccurrence matrix, done by graycomatrix() in the Image Processing Toolbox. What is a transition. If you have
0 0 0
0 1 0
0 0 0
how many transitions is that? One? Eight? Two? Four?

Transitions are indicated by
IM(:,1:end-1) ~= IM(:,2:end)
But how do you want this expressed as a "feature" ? If you want the index of them then the number could be different for each row.
