1. A computer-implemented method for training a view-based object recognition classifier, comprising:

  • generating an initial training set of images, wherein an image in the initial training set is generated based on a three-dimensional model and a set of one or more rendering parameter values;

    training the classifier using the initial training set;

    determining the classifier'"'"'s accuracy;

    determining a set of one or more local minima of the classifier'"'"'s output;

    for each local minimum in the set of local minima;

    determining a set of one or more rendering parameter values associated with the local minimum; and

    generating an additional image based on the three-dimensional model and the determined set of one or more rendering parameter values;

    training the classifier using the initial training set and the generated additional images.
