  • Publication number: 20240280462
    Abstract: The present disclosure discloses a data acquisition and analysis method based on diabetes data analysis and processing equipment, and relates to the field of diabetes data analysis and prediction. The equipment includes a computer, a placement rack and a flow cytometer. The mitochondrial membrane potential data in the neutrophil is performed independent evaluation and analysis. If the proportion of cells with increased mitochondrial membrane potential are in the neutrophil is greater than 70%, the person is at the risk of diabetes, otherwise the risk is lower, so that the subsequent development of diabetes in a person with normal blood glucose can be predicted, and the diabetes can be prevented in advance.

  • Patent number: 12067868
    Abstract: The present disclosure may provide a system. The system may obtain at least one pair of images from at least one pair of capture devices. Each of the at least one pair of capture devices may include a first capture device and a second capture device, and each of the at least one pair of images may include a first image captured by the first capture device and a second image captured by the second capture device. The system may determine first identification information of at least one first object in the first image and determine second identification information of at least one second object in the second image. Further, the system may determine at least one information pair by correlating at least a part of the first identification information and at least a part of the second identification information.

  • Publication number: 20240135710
    Abstract: The present disclosure relates to systems and methods for video analysis. The systems may obtain a video stream. For each of a plurality of frames in the video stream, the systems may determine a reference score corresponding to the frame based on a spatiotemporal feature of the frame. The spatiotemporal feature of the frame may associate a feature of the frame with a feature of at least one adjacent frame of the frame. The systems may determine, from the plurality of frames in the video stream, one or more target frames based on reference scores corresponding to the plurality of frames.

  • Publication number: 20240087343
    Abstract: A license plate classification method, a license plate classification apparatus and a computer-readable storage medium are provided. The method includes: performing a license plate recognition process on a first license plate image to obtain a license plate recognition result; performing an encoding process on the license plate recognition result to obtain a first license plate feature; performing a feature extraction process on the first license plate image to obtain a second license plate feature; and processing the first license plate feature and the second license plate feature through a classification network to obtain a first license plate classification result. In this way, an accuracy of license plate classification is improved.

  • Patent number: 11790699
    Abstract: The present disclosure provides a system and method for traffic violation detection. The system may determine a target object which should be given precedence with respect to a vehicle from one or more moving objects by performing an angle correction on the one or more moving objects, wherein the one or more moving objects are objects moving in a predetermined region. When it is determined that a moving direction of the target object is a moving direction towards middle of a road and a target vehicle passing through the predetermined region is not courteous to the target object, the system may mark a state of the target vehicle as a violation state.
