We first show several generated samples of an EqGAN-SA model on the LSUN Cat dataset, as below.
Then, we demostrate the spatial awareness of the EqGAN-SA generator via varying the spatial heatmaps. Specifically, we keep the latent codes unchanged and move the spatial heatmap at the coarsest feature level. The arrows indicate the movement direction, where the cat moves along with the varied heatmap.
To further show its ability of hierarchical manipulation, we move the heatmap at the finer levels. Different from the body movement, the change in 8 × 8 heatmap (two centers) mainly moves the cat eyes, and the change in 16 × 16 heatmap (four centers) leads to subtle movement of the cat ears. As highlighted in the rightest column, the cat ears subtly turn right while other parts, even the cat whiskers, remain unchanged.
