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

Theenergy problem is an important issue for the whole world and has received great attention in Chinasince China is both a big energy-consuming country and a country severely short of energy. Under theenergy and environmental pressure, China will take measures in the following four respects in orderto solve the problem of energy shortage: China will stick to the self-reliance principle for energysupply, since China has abundant coal resources, which have formed the mainstream of its energysupply. The coal resources account for 67 percent of energy supply and the self-reliant supply rateof coal has reached as high as 94 percent. China will take action to tap more resources and saveenergy consumption. China will attach greater importance to the development and exploitation ofrenewable energy resources. China will conduct international cooperation at an appropriate level.展开更多

文摘This paper proposes a technique for synthesizing a pixel-based photo-realistic talking face animation using two-step synthesis with HMMs and DNNs. 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.
