摘要:
A tracking start-and-stop determining unit of a tracking processing unit determines whether to start or stop tracking based on a predetermined condition. During tracking, a sampling unit 29 creates or eliminates particles using a probability density distribution estimated for the previous image frame. A first to nth model tracking units transit the particles according to motion models respectively assigned, and observe the likelihood of a candidate curve corresponding to each particle with respect to an edge image generated by an image processing unit. A tracking integration unit determines a motion model which causes the highest likelihood, and estimates a probability density distribution using an observation likelihood based on the motion model.

A photograph classification unit classifies the photographs for each scene in a music-feature information determination unit. A photograph feature acquisition unit identifies a feature of the photograph based on additional information of the photograph and a result of face recognition of the image. A tempo determination unit determines a tempo of music based on a time zone of image capturing, a range of the number of people captured in a photograph, the degree of smile, activities, etc. A melody determination unit determines information that confines a title, a feature value, a genre, etc., based on an event, a time zone, and a season at the time of image capturing, a city and a country in which the image capturing has occurred, etc. Based on the determined feature of the music, a music data output unit extracts and then presents matching music.

An edge extracting unit of a contour image generator generates an edge image of an input image using an edge extraction filter, etc. A foreground processing unit extracts the foreground from the input image using a background image and expands the foreground to generate an expanded foreground image. The foreground processing unit further generates a foreground boundary image constructed of the boundary of the expanded foreground region. A mask unit masks the edge image using the expanded foreground image to eliminate edges in the background. A synthesis unit synthesizes the masked edge image and the foreground boundary image to generate a contour image.

Candidate contour curves for a tracking object in the current frame are determined using a particle filter, based on the existence probability distribution of the tracking object in a frame which is one frame previous to the current frame. To match a candidate curve against a contour image of the current frame, a processing to search for the closest contour to the candidate curves is divided for each knot constituting the candidate contour curve and is executed in parallel by a plurality of processors. Each image data on a search region for each knot to be processed are copied from a contour image stored in an image storage to the respective local memories.

A positional data acquisition unit of an action detector acquires positional data indicating the position of an image of a light-emitting part of a light-emitting device held by a user in an image frame at each time step, and also acquires curve data for the head contour at each time step estimated as a result of visual tracking by a tracking processor. A history storage unit stores a history of the positional data for an image of a light-emitting part and the curved data for the head contour. A determination criteria storage unit stores the criteria for determining that a predefined action is performed by referring to the time-dependent change in the relative position of the image of the light-emitting part in relation to the curve representing the head contour. An action determination unit determines whether the action is performed based on the actual data.

A face detection processing unit performs a face detection process by rotating an image in increments of a predetermined angle and acquires a rotation angle at which a face is detected. An angle correction unit acquires an angle between the face and a shoulder by pattern matching and corrects the rotation angle of the image. A human-image orientation identification unit identifies a correct orientation of a human image based on the rotation angle. An image-characteristic analysis unit analyzes a frequency distribution and a brightness distribution of a non-human image. A non-human image orientation identification unit identifies the correct orientation of a non-human image based on distribution characteristics of a frequency of brightness with respect to an axis in a predetermined direction. An image-data updating unit incorporates information regarding the correct orientation in the image data.
