Method and system for embedding a unique and different digital watermark in digital contents for each access without increasing the overhear or load at the contents server. The contents server has a digital watermark-embedded contents storage unit for storing a plurality of digital contents where a different digital watermark is embedded, and a fingerprint performing unit for, adding to the digital contents the information specified using a bit row that is formed by a digital watermark being embedded for each part of the digital contents.

An object of the present invention is to provide a description method for efficiently representing contents of motion picture with a small data volume. The organization of the present invention (1) represents a trajectory of how each object has moved over time by using reference plane representing position information of each object, (2) sets a description unit based on a type of action of each object by using changes in shape of each object, (3) has actions of each object represented as each behavioral section, and (4) comprises a description facility capable of reading and interpreting definition of an object dependent on video contents, definition of classes of actions, and definition of interpretation of a scene by interaction of plural objects.

Method and device for describing video contents

A method and an apparatus for using the trajectory of an object to access video contents, for example, to specify and display a specific video image scene. Such a video contents access method comprises the steps of: extracting objects from video contents; displaying movements of the objects as trajectories on a specific projection screen; specifying locations on the trajectories; and accessing a desired scene of the video contents. An apparatus is so designed that it performs the above method.

Video contents access method that uses trajectories of objects and apparatus therefor

A method and image processing system are disclosed which simulate a hair style selected from among a number of prestored hair images in association with a facial image. The selected hair image includes an interior perimeter to be positioned adjacent to the facial image and a first plurality of associated feature points distributed along the interior perimeter of the hair image. A subset of the first plurality of feature points are disposed at locations at which the hair image is intended to abut, but not substantially overlap the facial image. The size and orientation of the selected hair image are automatically corrected with respect to the facial image. A second plurality of feature points distributed along the facial perimeter are then determined, which each correspond to one of the subset of feature points. One or more facial perimeter vectors are constructed by connecting neighboring feature points within the second plurality of feature points. Similarly, one or more hair perimeter vectors are constructed by connecting neighboring feature points within the subset of feature points. The hair image is automatically transformed by displaying each of a plurality of pixels within the hair image at a transformed location with respect to the facial perimeter vectors determined from an original position of the pixel with respect to the hair perimeter vectors. In response to the transformation of the hair image, the transformed hair image is displayed superimposed on the facial image.

Automated method and image processing system for hair style simulation

A user may input a motion as a query condition to a motion picture database to retrieve one or more motion picture segments (i.e., motion picture scenes) in which an object moves with a matching motion. A motion information database is built of motion vector sequences extracted from stored motion pictures. A motion is inputted as a query by moving a pointing device, such as a mouse, in a desired motion sequence, rather than as a query expressed in words or as a formula. The inputted motion sequence of the pointing device is converted to a motion vector sequence and compared with stored motion vector sequences to retrieve one or more scenes in which an object moves with a matching motion.
