  • Method for recognizing facial expressions based on adversarial elimination
    Patent number: 11804074
    Abstract: The present disclosure relates to a method for recognizing facial expressions based on adversarial elimination. First, a facial expression recognition network is built based on a deep convolutional neural network. On a natural facial expression data set, the facial expression recognition network is trained through a loss function to make facial expression features easier to distinguish. Then some key features of input images are actively eliminated by using an improved confrontation elimination method to generate a new data set to train new networks with different weight distributions and feature extraction capabilities, forcing the network to perform expression classification discrimination based on more features, which reduces the influence of interference factors such as occlusion on the network recognition accuracy rate, and improving the robustness of the facial expression recognition network.

  • DIGITAL FULL-BANDWIDTH DIRECT-FORWARDING RACON SYSTEM AND WORKING METHOD THEREOF
    Publication number: 20230283356
    Abstract: A digital full-bandwidth direct-forwarding racon system and a working method adopt a direct forwarding architecture, which combines a digital broadband DRFM real-time forwarding technology and an encoding response architecture with dots replacing a line. A transmitting antenna and a receiving antenna operate independently and simultaneously, and directly and indiscriminately encode and forward all of the radar query signals in an operating frequency band, thus preserving complete waveform information while realizing a Morse encoding of the response information. The digital full bandwidth direct forwarding racon system is equivalent to a target with a special target characteristic, where when a radar signal within the operating frequency band irradiates the target, an echo signal with a specified Morse encoding modulation characteristic would be generated.
