Normalization
Hierarchical Segmentation
Abstractn 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.
