In this context, segmentation is formulated as learning an image-driven policy for shape evolution that converges to the object boundary. The region selection decision is made based on predictions and uncertainties of the segmentation model being trained. 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. One challenge is differentiating classes with similar visual characteristics, such as trying to classify a green pixel as grass, shrubbery, or tree. Deep-learning-based semantic segmentation can yield a precise measurement of vegetation cover from high-resolution aerial photographs. 3 x 587 × 587) for a deep neural network. Deep Learning, as subset of Machine learning enables machine to have better capability to mimic human in recognizing images (image classification in supervised learning), seeing what kind of objects are in the images (object detection in supervised learning), as well as teaching the robot (reinforcement learning) to understand the world around it and interact with it for instance. on the image to improve segmentation and (2) the novel re-ward function design to train the agent for automatic seed generation with deep reinforcement learning. It contains an offline stage, where the reinforcement learning agent uses some images and manually segmented versions of these images to learn from. RL_segmentation. Hello seekers!
