Abstract: A system for reconstructing a magnetic particle image based on a pre-trained model aims to address the influence by point spread function and reduce the computational and time costs, which results in low reconstruction accuracy, or high acquisition time and computational costs for high-precision images. The system is implemented by: generating a simulation system matrix; pre-training a pre-constructed neural network model, and fine-tuning a pre-trained neural network model by performing a downstream task; and inputting real data corresponding to the downstream task into the pre-trained neural network model after fine-tuning, thereby playing an auxiliary role to acquire a high-quality reconstructed MPI image. The system fits the relationship between different harmonics, which helps enhance frequency-domain information.

Abstract: The present invention belongs to the technical field of computer vision, and proposes a lightweight real-time emotion analysis method incorporating eye tracking. In the method, gray frames and event frames that have synchronized time are acquired through event-based cameras and respectively input to a frame branch and an event branch; the frame branch extracts spatial features by convolution operations, and the event branch extracts temporal features through conv-SNN blocks; the frame branch has a guide attention mechanism for the event branch; and the spatial features and the temporal features are integrated by fully connected layers, The final output is the average of the n fully connected layer outputs, which represents the final expression. The method can recognize the emotional expression of any stage in various complex light changing scenarios; and in the case of limited accuracy loss, the emotion recognition time is shortened to achieve “real-time” user emotion analysis.
