Also known as: Image Creation, Novel View Synthesis
Creating novel images from models or learned distributions rather than recording with cameras or sensors.
DESCRIPTION
Image synthesis encompasses generating images from computational models, including graphics pipelines and neural generative methods. In graphics, physically based rendering synthesizes images from 3D scene descriptions. In machine learning, GANs and diffusion models learn image distributions and synthesize samples, often conditioned on text or other modalities. Neural radiance fields enable novel view synthesis from sparse observations. Use cases include design, simulation, content creation, and data augmentation. Considerations include realism, controllability, ethics, and provenance.
ALTERNATIVE DEFINITIONS
Wikipedia
Computer graphics deals with generating images with the aid of computers.

Wikipedia
Neural radiance fields (NeRFs) are neural networks that synthesize novel views of complex 3D scenes using a partial set of 2D images.
Highlights view synthesis as a specific synthesis subtask.
NVIDIA Developer
GANs are a class of machine learning frameworks that can synthesize realistic images by learning to generate samples that fool a discriminator network.
Emphasizes adversarial training for realism in synthesis.
