The present application relates to a kind of optimization method and system of timing diagram subgraph matching.The method includes: time block is carried out to original timing diagram, and the edge with same end point is aggregated and compressed in each time block to generate intra-block multi-edge object, to build block index in turn;Query graph with time constraint is received, with the edge in query graph as matching unit to execute search, and maintain current legal time window;In candidate generation stage, according to current to be matched data vertex pair and current legal time window, construct cache key, and carry out exploration in hotspot cache;If hotspot cache is not hit, then use current legal time window to locate target time block, and execute intersection operation in target time block to generate candidate multi-edge list;When current to be matched data vertex pair meets preset hotspot condition, the candidate multi-edge list is written into hotspot cache;Continue to execute search based on the candidate multi-edge list of hit or generated candidate multi-edge list, until outputting model matching result.

This invention provides a secure distributed data processing system and method for continuous-variable quantum key distribution. The system includes a main data processing computing unit and at least one secondary data processing computing unit. The main data processing computing unit periodically monitors the quantum link state and the state information of the secondary data processing computing units, and dynamically allocates data processing tasks to each secondary data processing computing unit. The secondary data processing computing units execute data processing and send the processing results back to the main data processing computing unit. This invention differentiates processing based on the apparent signal-to-noise ratio and normalized total noise characteristics of the data processing tasks, assigning high-computing-power secondary data processing computing units to high-computing-power secondary data processing computing units and low-computing-power secondary data processing computing units to low-computing-power secondary data processing computing units, thus fully utilizing the computing resources of multiple computing units and improving data processing efficiency.

The application provides an improved CLAHE short-wave infrared image real-time enhancement method based on FPGA. In view of the problems of low contrast, unobvious detail information and easy amplification of noise of InGaAs short-wave infrared imaging under low illumination, an improved limited contrast adaptive histogram equalization image enhancement algorithm is provided, and the optimal clipping threshold is automatically determined through an adaptive search mechanism, so that the local contrast is enhanced and the noise amplification is inhibited. The application can effectively improve the contrast and detail distinguishability of the short-wave infrared image, reduce the influence of noise, and is suitable for fields of short-wave infrared imaging systems, target identification systems and weak light vision systems.
