Figure 2

The visualization of the feature map extracted from the Conv5_3 layer in ResNet50. The first row is the original image in experiment datasets expressing various sentiments. The second row is the feature map of the Conv5_3 layer with a 7 × 7 matrix ranging from zero to one by processing the corresponding image. The third row is the artificial color map by integrating the original image and the feature map.
