Abstract: A color equalizing method between multiple cameras using a color checker chart is provided to be useful to 3D information restoration of a dynamic object, in a circumstance where it is not possible to perform a photographing process as moving one camera. In case of 3D data restoration, color differences generated between images simultaneously taken in various directions from plural cameras are calculated(S200-S202). With regard to the color differences, a relation between color models of each camera and a reference color model of a color checker cart is modeled and corrected to equalize colors between the multiple cameras(S203-S205). Coefficients of a color mapping equation between input image color information of the cameras and reference color information of the color checker chart are estimated. The estimated coefficients are applied to equalize input image color values of the cameras.

Abstract: A 3D facial model generation method and a device using multi-viewpoint image information are provided to control expression or facial postures through join control of a hierarchical structure, thereby offering an easy editing and modifying function of external facial shapes or expressions. An image input unit(102) inputs multi-viewpoint image information toward an expressionless face of a performer captured from plural cameras. An outer shape restorer(104) generates a mesh structure for outer shape expressions of a 3D facial model by using the inputted multi-viewpoint image information. A standard facial model transition unit(106) transfers standard model information to the generated mesh structure, and planarizes the mesh structure. The standard facial model transition unit enables operation of moving parts in each part. An intrinsic expression learning unit(108) locates joints of a hierarchical structure in the mesh structure.

Abstract: A system and a method for generating a 3D face modeling and animation using a single video camera are provided to transfer facial animation data of an actor into a facial performance of a virtual actor. A video camera(10) captures an image of an actor to generate video. A computer(20) processes the video of the actor inputted via the video camera and animate it. A digital signal processor(22) receives a facial performance video of a user from the video camera, converts the 3D facial performance video in an analog format into digital signals expressed by 0 and 1, so that the digital signals can be processed according to a mathematical operation. A face modeling unit(24) receives the video of the actor and models 3D face of the actor by frames. A D/A converter(28) converts the animation image of the 3D face processed by the face modeling unit into analog signals so as to be displayed via an output unit(30).
