Center node: "weakly supervised change detection in a pair of images"
  Abstract: Conventional change detection methods require a large number of images to learn background models. The few recent approaches that attempt change detection between two images either use handcrafted features or depend strongly on tedious pixel-level labeling by humans. #R##N#In this paper, we present a weakly supervised approach that needs only image-level labels to simultaneously detect and localize changes in a pair of images. To this end, we employ a deep neural network with DAG topology to { learn patterns of change} from image-level labeled training data. On top of the initial CNN activations, we define a CRF model to incorporate the local differences and the dense connections between individual pixels. We apply a constrained mean-field algorithm to estimate the pixel-level labels, and use the estimated labels to update the parameters of the CNN in an iterative EM framework. This enables imposing global constraints on the observed foreground probability mass function. Our evaluations on four large benchmark datasets demonstrate superior detection and localization performance.
