In this paper, a novel method of heterologous image registration method based on feature inertial following is proposed, which can perform high-precision and rapid registration of SAR image and optical image. The first image pair in the sequence is registered based on improved SURF feature to achieve high-precision registration. Based on this registration result, the other image pairs in the sequence are registered by the method of feature inertia following to achieve rapid registration. The proposed method makes full use of the correlation and gradient properties between image sequence frames. It maintains the registration accuracy of the preceding images, improves the registration speed greatly.

As the deployment scale of optical transport networks continues to expand, fault location which is an important function of ensuring the healthy operation of optical transport networks, becomes more and more important in optical network operation and maintenance. However, the expansion of the scale of the optical transport network and the deepening of the degree of heterogeneity have resulted in a large amount of fault data during the operation and maintenance of the optical transport networks. The traditional fault location technology lacks effective processing of a large amount of fault data and cannot meet the needs of the intelligent optical transport networks. In recent years, neural network algorithms have continued to develop, among which graph neural networks are particularly brilliant in processing graph-structured data. Using the reasoning ability of graph neural network, this paper proposes a fault location algorithm for optical transport network based on graph convolutional neural network. Taking the network nodes in the optical transport network as the data nodes in the graph convolution, and the fault data of the network nodes as the feature vector, the graph convolutional neural network aggregates the feature information adjacent nodes for each node. Through iteration, each node saves the feature information of each node to different degrees, so as to obtain the local structural features between nodes and the fault features of different nodes. The algorithm proposed in this paper has strong robustness in the case of network topology changes, that is, the algorithm can still adapt to the network when adding or deleting network nodes. The simulation results show that the fault location accuracy rate of the proposed algorithm can reach more than 95%, and the fault can be quickly located, and the location duration is about several milliseconds.

A multiplexing encoding method is proposed to achieve color complex amplitude holographic display. The band-limited angular spectrum method is utilized to calculate the diffracted wavefront of each channel and the double-phase method is used to encode the color-multiplexing hologram. Numerical simulations and optical experiments are performed to demonstrate the feasibility of the proposed method. It is expected that the proposed method could be widely applied in the holographic field in the future.
