摘要： An image processing apparatus and method produce sectional image data of a specimen in an arbitrary direction without deterioration of picture quality. A re-construction process produces volume data such that one of coordinate axes of a volume coordinate system such as the z axis is aligned with the principal axis of inertia of a specimen. When sectional image data of the specimen on a certain section are to be produced, from among all voxels which compose the volume data, those voxels whose z coordinates have predetermined values are read out, and the read out voxels are regarded as pixels. As a result, it is not necessary to interpolate pixels, and the deterioration of picture quality arising from interpolation of pixels is prevented.

摘要： Techniques for creating facial animation using a face mesh are provided. The techniques include determining a face mesh sequence. A portion of the face mesh sequence is then fitted to an image of the face. For example, a first frame of the face mesh sequence is fitted to the image. The face image is then projected onto the portion of the face mesh based on the fitting. Also, a hair model may be generated and fitted onto the face mesh sequence. Additionally, changes in color differences between sequences of the face mesh may be computed. The face mesh sequence is then played to create a facial animation sequence for the face image. The color differences that were created may also be added to the sequences as they are being played. Accordingly, the playing of the face mesh sequence creates a realistic facial animation of the image of the face.
