A coarse edge probability map is ﬁrst predicted by properly fused features extracted from original input images and further reﬁned by the features extracted from this coarse predication. Finally the segmentation is obtained by the post-processing on the reﬁned edge map.

The study of these protists has huge potential implications and benefits. 2016-03-01 · The agglutinated foraminifera selected different sized particles on hills and plains, reflecting the distinct granulometric characteristics of these settings. These characteristics (incorporation of coarse particles, test morphometry) could provide evidence for the recognition of ancient abyssal hill environments, as well as other palaeoceanographic settings that were characterised by enhanced current flow.

In the seminal work of Loeblich and Tappan (1988, 1989, 1992), Foraminifera were divided into 12 suborders that mainly differ by mineralogical and ultrastructural features of the test wall.
