As a representative example of the Chinese airport economy, the Zhengzhou Airport Economic Zone(ZAEZ) has played a significant leading and demonstrating role in the following fields: deepening the system reforms in an all-round way, promoting the "synchronization of five modernizations", building "one carrier and four systems", constructing "Four Henan", advancing the structural reform of supply-side and integrating the resources of the Henan airport. This article concludes: The supply-side structural reform needs to be accelerated and integrated into the international frontiers under "the Belt and Road" initiative. The ZAEA development has promoted the innovation of regional development patterns and showed the tendency toward the "five modernizations" of future regional development. The airport economy has developed rapidly based on the international aviation transportation system, and may change the traditional development patterns of regional centers located in coastal areas, and open a new era of regional development in the inland regions.展开更多

Global threshold binarization palmprint image is used in this paper,and the bio-morphological methods are used to get the sensitive area of palmprint image's positioning point,so as to extract the region of interest. The palmprint collection is realized on the FPGA chip,and this kind of collection method uses the DSP Builder toolbox to realize visual programming in Matlab / Simulink and achieve fast modeling and development. The practice proves that this method is simple,flexible and its equipment is portable and fast.展开更多
