Image simulations involve creating realistic or artificial images for different purposes, such as testing algorithms, training machine learning models, or conducting virtual experiments. This research area focuses on developing computer models and software that can generate images that mimic real-world scenarios or specific conditions. Image simulations can be used in a variety of fields, including computer graphics, medical imaging, remote sensing, and virtual reality. Researchers in this area often focus on techniques for accurately modeling light, textures, shadows, and other visual effects to create compelling and informative simulated images.
