What are GANs in Image Generation?
Generative Adversarial Networks (GANs) are a class of artificial intelligence frameworks designed for generating new images that closely resemble real-world data. Introduced by Ian Goodfellow in 2014, GANs consist of two neural networks: the generator and the discriminator. The generator creates images from random noise, while the discriminator evaluates them against real images, distinguishing between the two.
This adversarial process encourages the generator to improve its outputs progressively. The generator’s goal is to produce visually convincing images that can fool the discriminator, whereas the discriminator strives for higher accuracy in recognizing real images. This back-and-forth process leads to continuous enhancements in image quality over multiple iterations.
GANs have numerous applications in various fields, particularly in computer vision, where they are employed for tasks such as image synthesis, super-resolution, inpainting, and style transfer. For instance, they can generate high-resolution images from low-resolution inputs or create entirely new images based on learned characteristics from training data.
The versatility and effectiveness of GANs in producing high-quality images have revolutionized how we approach image generation, making them a cornerstone in current generative AI research.
