             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.",
