Abstract:
1. A recognition apparatus comprising: a generation unit configured to generate, for each of a plurality of discriminators, probability density distributions of correct and non-correct answers with respect a plurality of learning leaning images; a calculation unit configured to calculate, for each of the plurality of discriminators, an evaluation value based on the probability density distributions; a selection unit configured to select at least one of the plurality of discriminators based on respective evaluation values; a correction unit configured, if a ratio of a learning image with respect to a specific feature quantity is equal to or smaller than a predetermined ratio and a weight for the specific feature quantity is greater than a predetermined value, to correct a value of likelihood for the selected discriminator associated with the specific feature quantity to lower the value; a setting unit configured to set for the selected discriminator, a threshold of the value of likelihood corrected by the correction unit in association with a feature quantity; and a discrimination unit configured to extract a feature quantity from an input image and discriminate whether the input image includes a predetermined object by the selected discriminator, based on the likelihood associated with the feature quantity and the threshold set for the feature quantity.
