Table 2

Mutual information. Average of mutual information between each feature map and density map over all dataset’s images. Small columns show if the average of mutual information of each map is significantly different with two other maps. NS stands for not significant (), S stands for significant difference (0.001 < ), and HS stands for high significant difference ().
