A.5 IMPACT OF RANDOM SEED AND MODEL ROBUSTNESS
To further validate our model’s robustness to the impact of random seed, we inference with the same input conditions (i.e., text prompt and pose skeleton) and use different random seeds for generation. The results are shown in Fig. 5, which suggest that our proposed framework is robust to generate high-quality and text-aligned human images over multiple arbitrary random seeds.
A.6 BOARDER IMPACT AND ETHICAL CONSIDERATION
Generating realistic humans benefits a wide range of applications. It enriches creative domains such as art, design, and entertainment by enabling the creation of highly realistic and emotionally resonant visuals (Liu et al., 2022a;b). Besides, it streamlines design processes, reducing time and resources needed for tasks like graphic design and content production. However, it could be misused for malicious purposes like deepfake or forgery generation. We believe that the proper use of this technique will enhance the machine learning research and digital entertainment. We also advocate all the generated images should be labeled as “synthetic” to avoid negative social impacts.
