Morphological hierarchical segmentation and color spaces
Résumé
In this article, the color space influence on different methods of morphological hierarchical segmentation is studied. For this purpose, several experimental studies are carried out on hundred images of the ''Berkeley Segmentation Dataset and Benchmark'' (Berkeley). On one hand, four usual and representative color spaces (RGB, YCbCr, L*a*b*, IHSL) are considered. On the other hand, three different morphological hierarchical segmentation schemes are considered. These later are the quasi flat zones, the nonparametric hierarchical watershed (waterfall algorithm) and the nested homogeneous connections. As one could expect it, the different morphological hierarchical segmentation schemes do not have the same behavior in different color spaces. We conclude by proposing a ranking of color spaces according to the considered morphological hierarchical segmentation schemes.
