The ancient Lingnan area of China was influenced by nature and politics to form a prosperous goddess belief, which has been passed down in continuous development and still plays an important spiritual role for the people of the Lingnan area. The construction of the ancient Lingnan goddess database is an example of the digital integration of cultural resources in the Lingnan region. The knowledge map is used to build logic for the Lingnan ancient goddess database, and attribute extraction is used to collect relevant data. After data integration, the Lingnan ancient goddess resources are optimized and configured. Update data to create a research and understanding platform for different audiences and multi-level services. In the new era of promoting cultural construction in the Guangdong-Hong Kong-Macao Greater Bay Area, the effective application of the ancient Lingnan goddess database is conducive to building a cultural bay area, enhancing the cohesion and centripetal force of the people in Hong Kong and Macao, and thus strengthening the cultural identity of the Chinese nation.

Motion estimation (ME) and motion compensation (MC) are the key elements for frame rate up-conversion (FRUC) system. Fast and accurate motion estimation is the premise of high quality motion compensation. Unlike conventional unidirectional motion estimation which brings holes, overlaps and blocking artifacts, the bi-directional motion estimation does not produce any overlapped pixel or hole in the interpolated frames. As a result, the bi-directional motion estimation has better performance than conventional unidirectional motion estimation. This paper presents an efficient FPGA architecture targeting bi-directional motion estimation hardware implementation. This proposed architecture can achieve real-time processing for 1280x720@60Hz under 200MHz operating frequency. The design is described in Verilog HDL, verified in Virtex5 FPGA platform. Experimental results show that the proposed architecture has high performance and low cost for bi-directional motion estimation algorithm. This architecture can be used for video post-processing system.
