14. MergeTalk: Audio-Driven Talking Head Generation From Single Image With Feature Merge

Author

Gao, Jian, Shu, Chang, Zheng, Ximin, Lu, Zheng, and Bao, Nengsheng

Abstract

Audio-driven talking head generation has wide real world applications but remains challenging due to the problems such as audio-lip synchronization, head poses, identity preservation, video quality, etc. We propose a novel two-stage framework that uses explicit 3D face images rendered from a 3D model based on the audio input, as intermediate features. We devise two independent 3D motion parameter generation networks to generate expression and pose parameters for the popular 3DMM model to solve the audio-lip synchronization problem and natural head poses without losing identity information. To improve the final talking head quality such as avoiding facial distortion and artifacts, we propose a novel face feature merge network to accurately extract and fuse the background, identity information, facial texture from the source image, and the lip movements and head poses from the 3D face images, and generate the final videos based on generative adversarial networks. Extensive experiments show that our framework outperforms the SOTA methods in several aspects and has good generalization ability.

Abstract

Summary: The battery box is the structure that comprises the battery cells and its casing. It is designed to fix and protect the battery module. During the actual driving, there exists stress and resonance on a battery pack and its outer casing due to external vibration and shock. The safety of an electric vehicle largely depends on the mechanical characteristics of its battery pack. Besides, a lighter weight electric vehicle has a longer driving range, which makes it much more popular in vehicle market. In this paper, a comprehensive design procedure based on multi‐objective optimization and experiments is applied to compare the maximum equivalent stress and resonance frequency on a battery pack casing with different materials (DC01 steel, aluminum 6061, copper C22000, and carbon nanotube [CNT]) under bumpy road, sharp turns, and sudden braking conditions to obtain the best material. Moreover, CNT is proved to be the best material considering all the performance standards. Response surface optimization design method is adopted to get an optimal design of the battery pack casing. Optimization results conclude that the maximum equivalent stress can be reduced from 3.9243 to 3.2363 MPa, and the six‐order resonance frequency can be increased from 722.65 to 788.71 Hz. Experiments are carried to validate the mechanical performance of the optimal design; the deviation between the simulation and experimental results is within the tolerance. [ABSTRACT FROM AUTHOR]

Abstract

The current development of wind power in China was presented in this paper. Many regions such as Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region and southeast coastal region, etc. in China have abundant wind energy resource. At the same time, the utilization of wind power in China has been developing quickly and its prospect is promising in spite of many some obstacles. With the implementation of the Renewable Energy Law, some previous obstacles have been or are being eliminated. Much investment and many enterprises start to enter this field. In spite of this, there still exist some financial and technological obstacles. One of the technological obstacles is the stability of local power grid owing to the increasing proportion of the wind power capacity. Because the centralized development mode of wind power was adopted, the quick fluctuation of wind speed will influence the voltage and frequency stability of local power grid. In addition, large wind farm has little dispatching ability because of the uncontrollability, randomness and fluctuation of natural incoming wind. To erase these obstacles, a novel hybrid power system combining wind farm and small gas turbine power plants is discussed.
