Optimization of Motion Estimation Algorithm Based on FPGA Hardware System and Video Tracking

Motion Estimation (ME) is a computationally expensive step in video tracking. A thorough search technique produces the best execution time and the best accuracy. Computational burden, many fast search algorithms limit and report the number of places to search. Motion estimation, analysis of image sequences, computer vision, tracking a target, and is a critical process in a wide range of fields and applications such as video coding. Precision motion estimation lowers significantly bit rate, but can require a complexity of higher computational. This is different reference frames, sub-pixel estimation, and video compression standards, including techniques such as variable block size, MPEG, especially true for a new generation. Only the motion estimation in H.261 is limited to an integer pixel accuracy, rather than the pixel grid, not in the object is often located, move to move between pixels. The system proposed in the motion vector optimization motion estimation (OME) pixel accuracy. By estimating the amount of displacement at a finer resolution, improve prediction, it can expect better performance than motion estimation using an integer pixel precision. Optimization motion estimation (OME) and the compensation method is very similar to that employed in other standards. The main is that block-based motion estimation and compensation is suitable for optimization structures in MPEG-4. Motion estimation (ME) is one of the most computationally-intensive companies in the video compression technology. Video compression algorithm, MPEG1, MPEG4, such as H.261 and H.264, a lot of the standard used. Improved compression performance. Energy effective motion estimation technique is reduced to the rest of the frame involved in motion compensation.     

External Incentive Mechanism Research on Knowledge Cooperation-Sharing in the Chinese Creative Industry Cluster

The creative industry is a knowledge-based industry, but it is difficult and complex to create knowledge for enterprises. The principle of cooperation-sharing posits that companies’ limited resources prohibit them from gaining a competitive advantage in all business areas. Therefore, cooperation-sharing can help businesses overcome this hurdle. Cooperation-sharing expedites economic development, breaks the barrier of independent knowledge creation, and enhances resource utilization. However, the effectiveness and stability of knowledge cooperation-sharing are key problems facing governments and other regulators. This study can help regulators promote honesty in enterprise cooperation-sharing. Based on the hypothesis of bounded rationality, the evolutionary game theory was used to construct the “Enterprises–Informal Institutions–Government” tripartite game matrix. Next, based on this game matrix, a simulation analysis method was used to analyze the effects of external incentives on the stability of evolutionary strategies. The analysis shows that the strategic choice of the “Enterprises–Informal Institutions–Government” tripartite game could be affected by the initial state strategy choices of the other two players, but more influential were the cost and external incentive levels of the game players. The results indicate that the government and informal institutions should regulate enterprises with a rational external incentive mechanism that boosts the enterprises’ incentive to cooperate honestly. Thus, an effective external incentive mechanism can significantly improve the probability of enterprises behaving honestly in cooperation-sharing and promote the development of the creative industry.

A causal knowledge-based expert system for planning an Internet-based stock trading system

This study describes a causal knowledge-based expert system for planning an Internet-based stock trading system, abbreviated CAKES-ISTS. The case base of this system consists of the qualities that promote ISTS use, two specific facets of ISTS use (stock amount purchased and frequency of use), and user satisfaction. Planning ISTS requires consideration of the complex causal relationships between system qualities, system use, and performance (i.e., user satisfaction). This study also examines the factors affecting the level of system usage and performance. First, this study uses a fuzzy cognitive map (FCM) to develop the causal knowledge base of the expert system for ISTS planning. Second, this study uses structural equation modeling to estimate the relevant relationships among FCM components as well as their direction and strength. Third, this study develops rules based on system qualities to predict the usage and performance level of ISTS, allowing the identification of the qualities essential to enhance system usage and performance. This clearly shows how effective ISTS planning is possible through the inference process provided by CAKES-ISTS.
