1. An information processing device comprising: a learning unit that performs, using an action performed by an object and an observation value of an image as learning data, learning of a separation learning model, that includes, a background model that is a model of the background of the image; and one or more foreground model(s) that is a model of a foreground of the image, which can move on the background, in which, the background model includes a background appearance model indicating the appearance of the background; and at least one among the one or more foreground model(s) includes, a transition probability, with which a state corresponding to the position of the foreground on the background is transitioned by an action performed by the object corresponding to the foreground, for each action; and a foreground appearance model indicating the appearance of the foreground.
