    Abstract: The disclosure is training a recognizer that outputs a recognition result by using a time series of feature data as an input. In addition, the disclosure is setting a data range whose length is a specified time width to a set of feature data to which a time is added, and selecting a specified number of pieces of the feature data from within the data range; adding a teacher label corresponding to the recognition result to the selected plurality of pieces of feature data, whose time order is retained, based on information regarding the plurality of pieces of feature data; and training the recognizer by using, as training data, a set of the plurality of pieces of feature data, whose time order is retained, and the teacher label.

    Abstract: In order to acquire recognition environment information impacting the recognition accuracy of a recognition engine, an information processing device 100 comprises a detection unit 101 and an environment acquisition unit 102. The detection unit 101 detects a marker, which has been disposed within a recognition target zone for the purpose of acquiring information, from an image captured by means of an imaging device which captures images of objects located within the recognition target zone. The environment acquisition unit 102 acquires the recognition environment information based on image information of the detected marker. The recognition environment information is information representing the way in which a recognition target object is reproduced in an image captured by the imaging device when said imaging device captures an image of the recognition target object located within the recognition target zone.

    Abstract: An approximate positions-of-people determination means determines, for each partial area, approximate positions of people on an image on the basis of information about the partial area. A states-of-people estimation means, in addition to predicting the current states of particles from the states of particles indicating past states of people and stored in a storage means, adds new particles and evaluates the likelihood of the states of predicted particles and the added particles on the basis of an observation model generated for the observed people to update the weights of the particles, performs particle re-sampling at a probability proportional to the weights of those particles, and outputs the states of the obtained particles as a flow of people.
