We introduce facial expression parameters as an intermediate representation that has a good correspondence with both of the input contexts and the output pixel data of face images. The sequences of the facial expression parameters are modeled using context-dependent HMMs with static and dynamic features. The mapping from the expression parameters to the target pixel images are trained using DNNs. We examine the required amount of the training data for HMMs and DNNs and compare the performance of the proposed technique with the conventional PCA-based technique through objective and subjective evaluation experiments.展开更多
WALK around any Chinese city and one of the most common sights you will see are people chatting into cellphones or busy focusing on their handsets, often to the exclusion of all else.

TEN-year-old Panashe Jere, a sixth grader in Malawi s capital city Lilongwe, seems no different from other boys of his age. Slight and quiet, he borders on being shy. But set him among his toolscomputers.

The energy problem is an important issue for the whole world and has received great attention in China since China is both a big energy-consuming country and a country severely short of energy. Under the energy and environmental pressure,China will take measures in the following four respects in order to solve the problem of energy展开更多
