U-Net is a convolutional neural network that was developed for biomedical image segmentation at the Computer Science Department of the University of Freiburg.[1] The network is based on a fully convolutional neural network[2] whose architecture was modified and extended to work with fewer training images and to yield more precise segmentation. Segmentation of a 512 × 512 image takes less than a second on a modern GPU.
The U-Net architecture has also been employed in diffusion models for iterative image denoising.[3] This technology underlies many modern image generation models, such as DALL-E, Midjourney, and Stable Diffusion.
