Figure 10. Visualization of feature maps in the overall architecture.

(a) A subset of original images, which had been performed on a localization processing, were selected from the test set for illustrating pose variations (Row 1&2), inter-species similarity (Row 3&4) and intra-class difference (Row 5). These images were then used in our recognition tasks, and in (b–f), we show the top activated feature maps of the corresponding original images after layers Conv1–5. The brightness and contrast were enhanced for each feature map for the best view. Original images are provided by Huan Zhang.
