An image processing apparatus obtains a difference between a partial region of an input image and a partial region of a background image, stored in a storage device, corresponding to the partial region of the input image, determines whether each partial region of the input image is a moving body region or a background region based on the difference, and combines the partial region of the input image determined as the background region and the partial region of the background image corresponding to the partial region of the input image to update the background image.
摘要:
When discriminating a plurality of types of objects, a plurality of local feature quantities are extracted from local regions in an image, and positions of the local regions, and attributes according to image characteristics of the local feature quantities are stored in correspondence with each other. Then, object likelihoods with respect to a plurality of objects are determined from attributes of feature quantities in a region-of-interest, an object whose object likelihood is not less than a threshold value is determined as an object candidate, and whether an object candidate is a predetermined object is determined.
