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.

The utility model discloses an adjustable multi -point self -centering precision chuck belongs to machining equipment technical field, is aimed at the problem that driving process can not guarantee clamping stability and can not keep stable synchronous clamping operation of each clamping jaw, including bottom plate, mounting seat and support rod, the mounting seat is provided with the centering mechanism, the bottom plate top fixedly connected with motor, and the motor upper end fixedly connected with the pivot, and the pivot is rotatoryly arranged on the mounting seat and is connected with the centering mechanism, the utility model discloses the centering mechanism that sets up, cooperation motor's drive operation makes workpiece when carrying out centering clamping on the mounting seat upper portion, can stably on its upper portion clamping, and further guarantees the centering effect and the stability of processing, through the centering mechanism that sets up, makes each locating piece can keep synchronous centering positioning work, improves the synchronism of workpiece centering process, ensures that workpiece can be accurately centered operation, thereby improves the practicality of device.

The application discloses a foot pad positioning module, which comprises a base, a foot pad boss supported on the base, the foot pad boss being provided with a foot pad supporting surface, a plurality of positioning members protruding above the foot pad supporting surface and surrounding a foot pad fixing position with the foot pad supporting surface, a spacing area being formed between adjacent positioning members, and a centering assembly comprising a centering member, the end of the centering member being capable of approaching or moving away from the spacing area. The foot pad profiling positioning area is formed by the foot pad boss and the plurality of positioning members, and the centering assembly is arranged to fill the spacing area between the positioning members, so that the centering effect is achieved on the foot pad, the fixing effect of the foot pad is further improved, the foot pad is always in the same position when being transmitted to the next process, and the assembly effect and the yield are improved.

The simple crucible centering and leveling device comprises a centering platform, the upper surface and the lower surface of the centering platform are completely parallel, a groove is formed in the bottom of the centering platform, a bolt fixing hole is formed between the groove and the upper surface of the centering platform in a penetrating mode, and a coaxial sleeve is arranged at the top of the centering platform. A reducing section is arranged at the upper end of the outer wall of the sleeve, and the diameter of the reducing section is gradually increased from top to bottom. And a chamfering structure is arranged on the outer wall of the top of the reducing section. The bottom cross sectional area of the sleeve is smaller than the area of the upper surface of the centering platform. The crucible centering device is simple in structure, the crucible, the water box and the guide column can be rapidly and simply centered, and the centering effect is good.
