The learning phase is based on reinforcement learning (RL). 309–318. (https://github.com/multimodallearning/pytorch-mask-rcnn). To explain these training styles, consider the task of separating the This is the code for the paper Communicative Reinforcement Learning Agents for Landmark Detection in Brain Images. Yang, L., Zhang, Y., Chen, J., Zhang, S., Chen, D.Z. Springer, Cham (2017). Eng. Although deep learning has achieved great success on … Experiment 3: employing the difference IoU reward as the final immediate reward. Active learning, which follows a strategy to select and annotate informative samples, is an effective approach … 165.22.236.170. Many studies have explored an interactive strategy to improve the image segmentation performance by iteratively incorporating user hints. An important application is estimation of the location and volume of the prostate in transrectal ultrasound (TRUS) images. For example, fully convolutional neural networks (FCN) … This is the code for "Medical Image Segmentation with Deep Reinforcement Learning". We conduct experiments on two kinds of medical image data sets, and the results demonstrate that our method is able to learn better strategy compared with the existing hand-design ones. Secondly, medical image segmentation methods Deep neural network (DNN) based approaches have been widely investigated and deployed in medical image analysis. In this paper, we propose a deep reinforcement learning algorithm for active learning on medical image data. But, due to some factors, such as poor image contrast, noise and missing or diffuse boundaries, the ultrasound images are inherently difficult to segment. RL-Medical.
