Object segmentation defines spatially coherent objects based on pixel classification results. In perClass Mira, many operations and analysis types extend naturally to objects. For example, we may wish to compute spectral index only on objects of interst, model quality of some objects using regression analysis or export mean spectrum per object for further research.


The first step to apply object segmentation is to define one or more foreground classes. This can be done using Image list context menu and selecting Flag class as foreground. Alternatively, the 'F' shortcut toggles the foreground flag for the currently selected class in the Class list


The Objects panel presents a separate section where objects are defined (object segmentation) and where objects are classified
