The user then selected the best mask for each of 10 training images. A standard model such as ResNet, VGG or MobileNet is chosen for the base network usually. Iterative refinements evolve the shape according to the policy, eventually identifying boundaries of the object being segmented. Introduction. This algorithm is used to find the appropriate local values for sub-images and to extract the prostate. The bright red contour is the ground truth label. After all, there are patterns everywhere. 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. Work fast with our official CLI.
