  • Patent number: 11969145
    Abstract: A medical endoscope image recognition method is provided. In the method, endoscope images are received from a medical endoscope. The endoscope images are filtered with a neural network, to obtain target endoscope images. Organ information corresponding to the target endoscope images is recognized via the neural network. An imaging type of the target endoscope images is identified according to the corresponding organ information with a classification network. A lesion region in the target endoscope images is localized according to an organ part indicated by the organ information. A lesion category of the lesion region in an image capture mode of the medical endoscope corresponding to the imaging type is identified.

  • Patent number: 11359670
    Abstract: The present invention provides a transmission roller, a pin-teeth cycloid reducer with the same and a bearing. The transmission roller comprises a hollow roller which is made by spirally and closely winding a steel strip or a steel wire, and the length of the hollow roller remains unchanged when both ends thereof distributed along the axial direction are squeezed. When the hollow roller is subjected to external pressure, the ends thereof will not be easily damaged, and will not extend to the middle part during use, thus having a long service life.
