Abstract
An image recognition device includes an image acquiring unit configured to acquire an image, and an object recognition unit configured to calculate gradient directions and gradient values of intensity of the image acquired by the image acquiring unit, to scan the gradient values of each acquired gradient direction with a window, to calculate a rectangular feature value, and to recognize a target object using a classifier based on the rectangular feature value.
