Deep Learning for Image Processing
Perform image processing tasks, such as removing image noise and performing image-to-image translation, using deep neural networks (requires Deep Learning Toolbox™)
Deep learning uses neural networks to learn useful representations of features directly from data. For example, you can use a pretrained neural network to identify and remove artifacts like noise from images.
