Dear Fellow Scholars, this is Two Minute Papers with Dr. Károly Zsolnai-Fehér. Today, we have a selection of learning-based techniques that can generate images of photorealistic human faces for people that don’t exist. These techniques have come a long way over the last few years, so much so that we can now even edit these images to our liking, by,... Read More

Questions & Answers

Q: How does StarGAN 2 generate photorealistic human faces?

StarGAN 2 uses learning-based techniques to generate images that morph from a source person to a target subject, capturing attributes like pose, nose type, and mouth shape accurately.

Q: Does StarGAN 2 work for other domains besides human faces?

Yes, StarGAN 2 can also transform animal images, such as cats morphing into dogs, with accurate features like gaze direction and face shape translation.

Q: How does StarGAN 2 handle occlusions in images?

StarGAN 2 is able to distinguish occlusions from the actual subject and can generate images without translating the occlusion, showcasing its ability to understand and interpret features accurately.

Q: What makes StarGAN 2 different from previous techniques?

StarGAN 2 creates multiple latent spaces for different domains, allowing it to generate images across various categories and accurately translate features like ears, eyes, and noses between different animals.
