The left-most local minimum (LLM) method has been proposed to avoid the overtruncation of data with MSER. The left-most local minimum is selected as the truncation point, rather than the usual global minimum. However, we found that this produced very early truncation points when applied to the initial sequence generalised MSER methods, because the curves of MSE against truncation point were noisy and had early minima. For our data, it would be unhelpful to apply this to the other truncation heuristics, because they already showed a tendency towards early truncation.
