The Image Panel contains a list of images contained in the current project.
Toggle selection state of individual images in order to control their use as master images during matching. Please note, that deselected images can still be used as slave during matching regardless of their activation status.
In order to process only a certain subregion of your dataset, it is recommended to use the area parameter rather then selecting master images.
Hover over images to get additional information about image dimension and image bit depth.
