abstract = "n recent years, many algorithms based on hierarchical segmentation
were proposed. However, there has a need to represent their
obtained results. The saliency map approach is an example of
algorithm which allows the visualization of the hierarchy by
defining a relevance to the contours found in the image. And, in
order to visualize the segmentation result, a normalization is
needed. Even though the classical approaches are satisfactory,
there are two major problems: (i) the normalization does not
prevent oversegmentation; (ii) it is not possible to alter the
normalization to achieve better results. In this paper, we have
studied a normalization by a sigmoid function, we analyzed its
impacts as a filtering step, and as a final (visualization) one,
and we also examined how the gradient impacts on the final result
in accordance with our proposal. Experimental results show that,
for both gradient functions, the pre-filtering step has better
results than classical approaches.",
