StyleGAN, developed by NVIDIA, is a generative adversarial network (GAN) architecture that enables the synthesis of high-quality, photorealistic images. By introducing a style-based generator, it allows for unprecedented control over the visual attributes of generated images, facilitating applications in art, design, and entertainment. Subsequent versions, such as StyleGAN2 and StyleGAN3, have further enhanced image quality and addressed artifacts, solidifying StyleGAN's status as a pivotal tool in AI-driven image generation.
