  • Publication number: 20240331355
    Abstract: The present disclosure provides a synchronous processing method, system, storage medium and terminal for image classification and object detection. The method includes the following steps: inputting the image into a neural network to perform a first convolution operation to obtain a first feature map; performing sequentially a second convolution operation, a pooling operation and a nonlinear function activation operation on the first feature map to obtain a second feature map, obtaining the object detection result of the image based on the second feature map; performing in sequence a global average pooling operation and a full connection operation on the first feature map to obtain the classification result of the image. The synchronous processing method, system, storage medium and terminal for image classification and object detection of the present disclosure simultaneously perform image classification and object detection through the same neural network, thus effectively reducing system load.

  • Patent number: 11316160
    Abstract: A supercapacity lithium ion battery cathode material, a preparation method therefor and an application thereof. The supercapacity lithium ion battery cathode material consists of a transition metal-containing lithium ion cathode material and carbon which is coated on the surface of the lithium ion cathode material. The transition metal on the surface of the lithium ion cathode material is coordinated with carbon by means of X—C bonds to form transition metal-X—C chemical bonds, such that carbon stably coats the surface of the cathode material, wherein C is SP3 hybridization and/or SP2 hybridization, and X is at least one selected from among N, O and S.
