Does it support segment a certain type of objects by click one of them?

for example, find all cats by click one of them?

Yes, SAM is able after a sufficient number of inputs to deduce what type of object should be segmented and will subsequently do so. However, that does usually not happen after the first click. Usually after you clicked on 2-3 cats then it will understand to segment all cats.
