Object localization : non-labeled object

Hi ! I understood the global principales of object localization : it set Pc between 0+ and 1 and then C1, C2 or C3 equal to 1.
But what happens when non of this objects are in the image ? If there is a non-labeled object. Like a cat for exemple. Is Pc set to 0 too (like there is nothing to detect) ?

Thx !

Your understanding is correct. When we have no objects of interest in the image, Pc = 0. The entire image is considered to be made of background and none of the other outputs matter.
