After running alignment, several smaller components can be created if there is not enough overlap between images. If the count of cameras in these components is smaller than the threshold of a minimum number of images in a component, they will be combined into one entity in the 1Ds view, which is expandable. This will also activate the Small Components button in the Settings part of the SCENE 1D/VIEW tab if small components were computed.
Grouping smaller components into one entity makes it easier to navigate in the 1Ds view if there is a larger number of components,
although it also makes it easier to delete those components. After setting a mouse pointer over Small components in the 1Ds
view a button will show. This removes all small components from the application.
This action can be undone, and is also re-doable.
