From: InSegtCone: interactive segmentation of crystalline cones in compound eyes
Auto-segmented crystalline cones in the compound eyes of three arthropods. The eyes of Apis mellifera (ai), Bombus terrestris (aii) and Pieris napi (aiii) were divided respectively into 4, 12 and 9 subregions. Overview of the cones segmented with InSegtCone (each labelled with a different colour) from the front (bi-iii) and the side (ci-iii), as indicated by the volume renderings of the species’ heads (grey images). The border of the external surface of the cornea is represented in black. The miniature in each left corner indicates the topology of the cone density ratio. A ratio locally equal to one means that all expected cones were auto-segmented. (di-iii) Detailed view of a portion of the auto-segmented cones
