2015 Multimedia Systems  
It significantly improves the counting of elements per class. We further propose visualization designs for understanding and evaluating the classification uncertainty.  ...  This work was developed to address the needs of ecologists studying fish population abundance using computer vision, but generalizes to a larger range of applications.  ...  Such visualizations can support users in acquiring a better understanding of the uncertainty and of the underlying computational processes.  ...
