Utilizing generative adversarial networks (GANs) for creating realistic images through AI has revolutionized the field of computer vision and image synthesis. GANs, a class of artificial intelligence algorithms introduced by Ian Goodfellow and his colleagues in 2014, have gained immense popularity for their ability to generate high-quality, photorealistic images that can be indistinguishable from real photographs. In this article, we will delve into the intricacies of GANs, exploring their architecture, training processes, challenges, and applications in image synthesis. Additionally, we will discuss the ethical considerations surrounding AI-generated images and examine the future directions of GAN research in pushing the boundaries of realistic image creation through artificial intelligence.
