Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for training a neural network to perform segmentation. One of the methods includes obtaining a sequence of input images each corresponding to a time step; and at each of a plurality of the time steps: processing a first input image of the sequence that corresponds to the time step using the neural network to generate a new network output that identifies foreground pixels and background pixels of the first input image; obtaining a previous network output generated at a previous time step that identifies foreground pixels and background pixels of a second input image of the sequence; and determining a difference between the new network output and the previous network output; and determining an update to network parameters of the neural network using the difference determined at each time step of the plurality of time steps.
