In one example implementation according to embodiments of the invention, a computer-implemented method includes identifying a first discrete element of the composite object from a first image. The method further includes identifying the composite object based at least in part on the first discrete element of the composite object. The method further includes determining whether a category associated with the composite object is a category of interest. The method further includes, based at least in part on determining that the category associated with the composite object is a category of interest, increasing a discrete element count. The method further includes determining whether the discrete element count meets a threshold. The method further includes, based at least in part on determining that the discrete element count exceeds the threshold, performing a mitigation action.
