A novel fMRI site noise automatic correction algorithm using generative adversarial networks
The present application belongs to the field of medical image processing and artificial intelligence, and proposes a new fMRI site noise automatic correction algorithm using a generative adversarial network, including a feature generator, a site noise feature generator, a feature fusion generator and a discriminator; compared with the traditional Fader network, the site label automatic coding module is added, which can automatically project and encode the site label of the data into an image, and separate it from the original image, thereby realizing the automatic correction of the multi-center effect of the fMRI data, avoiding the artificial site noise coding assumption, and more accurately identifying and eliminating the multi-center effect.

Intelligent centering method and system for hedge trimmer
The present invention relates to the field of hedge trimming control, and more specifically, to an intelligent centering method and system for hedge trimmers. The method first obtains the current tool vibration coefficient based on the tool's short-term tilt angle, operating power, acceleration data, and point cloud position changes on the trimming path. The current tool centering coefficient is obtained based on the depth value difference between the pixel points on the edge of the tool area on one side of the trimmed hedge area and the pixel points in the trimmed hedge area, as well as the correlation between the depth value changes of the pixel points between each reference line and the center line of the tool area. Based on the tool vibration coefficient and the tool centering coefficient, the trimming posture deviation is obtained. The hedge offset is obtained based on the length of the branch edge line and the hue and saturation values of the pixel points in the untrimmed hedge area. The trimming posture deviation and the hedge offset are combined to perform real-time centering control on the hedge trimmer. The present invention can improve the centering effect of the hedge trimmer.
