Image synthesis is the process of creating new images from scratch or modifying existing ones using algorithms and computer programs. This technique often employs methods like deep learning and neural networks to generate realistic visuals, allowing for the creation of art, photographs, or even entirely new scenes that do not exist in reality. One popular application of image synthesis is in the field of computer graphics, where it enhances video games and movies by generating lifelike characters and environments. Additionally, it is used in virtual reality and augmented reality to create immersive experiences, blending digital content with the real world.
