摘要： A mounting structure of a three-cylinder engine is mounted in a car body transversely but is installed on engine and transmission mounts built on opposing sides in the width direction of the vehicle so that its weight can be supported, wherein a roll mount controls roll moment. The center of mass of the engine and the transmission is the center of rotation where a longitudinal pitch axis, a lateral roll axis and a vertical yaw axis all cross each other, but the roll mount is combined with the engine or the transmission so that the combination point lies on the yaw axis. The mounting structure can improve the NVH performance by suppressing the pitch moment and inducing the yaw moment and by more efficiently insulating the vibration caused by the yaw moment while maintaining the common platform.

摘要： In a three-dimensional model-based coding system, a shape of mouth, especially, a shape of lip, among a shape of face, has an important visual information. As each person has the different shape of lip, however, it is desirable to transform the shape of lip based on an individual person. First, a characteristic three-dimensional lip model based on the individual person is generated by matching a three-dimensional lip model to a basic lip of the individual person. Subsequently, the characteristic three-dimensional lip model is converted into a two-dimensional lip model and rotated according an angle of a actual lip image. In case that the person is talking, the two-dimensional lip model is reconstructed based on a recognized syllable. Finally, a difference between the two-dimensional lip model and the actual lip image is calculated. As not a whole real lip image but the difference between the actual image and the two-dimensional lip model similar to the actual lip image is transmitted, the amount of transmission data can be reduced.

摘要： An apparatus for predicting a current frame signal included in an image signal based on a reference frame first detects a panning vector representing a spatial displacement between the current and the reference frames. Once the panning vector is detected, a predicted frame containing a substitutable region and an unsubstitutable region is determined based on the panning vector and the reference frame, and then an amplitude of the panning vector is compared with a reference value. Subsequently, a predicted current frame signal is generated as the result of the current frame prediction process in response to the result of the comparison. If the amplitude of the panning vector is smaller than the reference value, the predicted current frame signal is produced by padding pixel values of the substitutable region which are located along a boundary between the substitutable region and the unsubstitutable region into the unsubstitutable region. Meanwhile, if the amplitude of the panning vector is greater than or equal to the reference value, the predicted current frame signal is created by using a block matching technique for the unsubstitutable region based on the current and the reference frame signals.
