When using a CNN for semantic segmentation, the output is also an image rather than a fixed length vector. An agent learns a policy to select a subset of small informative image regions -- opposed to entire images -- to be labeled, from a pool of unlabeled data. If you believe that medical imaging and deep learning is just about segmentation, this article is here to prove you wrong. One challenge is differentiating classes with similar visual characteristics, such as trying to classify a green pixel as grass, shrubbery, or tree. Image Source “My life seemed to be a series of events and accidents. To create digital material twins, the μCT images were segmented using deep learning based semantic segmentation technique. There are many ways to perform image segmentation, including Convolutional Neural Networks (CNN), Fully Convolutional Networks (FCN), and frameworks like DeepLab and SegNet. In this context, segmentation is formulated as learning an image-driven policy for shape evolution that converges to the object boundary. https://debuggercafe.com/introduction-to-image-segmentation-in-deep-learning Nowadays, semantic segmentation is one of the key problems in the field of computer vision.
