VGG-19 classifications for black object silhouettes Part 1.
The leftmost column shows the image presented to VGG-19. The second column from the left shows the correct object label and the classification probability produced for that label. The other five columns show probabilities for the network’s top five classifications, ordered left to right in terms of the probability given by the network. Correct classifications are shaded in blue.
