Title:
IMAGE RECOGNITION DEVICE
Document Type and Number:
Japanese Patent JP2016207107
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To accurately discriminate a subject even when a background is complicated by selecting a discriminator in accordance with complexity calculated from a partial region in a detection window when the background is complicated in the discrimination processing of the subject.SOLUTION: An image discrimination device for discriminating a desired object from an input pattern includes: featured value calculation means for calculating a featured value from the input pattern; discriminator storage means for storing a discriminator for discriminating whether or not the input pattern is a target; partial region setting means for setting a partial region in the input pattern; complexity calculation means for calculating complexity from the partial region; discriminator selection means for selecting the discriminator stored in the discriminator storage means in accordance with the complexity; and discrimination processing means for discriminating whether or not the input pattern is the target from the output of the featured value calculation means and the discriminator selected by the discriminator selection means.SELECTED DRAWING: Figure 1
