  • Publication number: 20230122927
    Abstract: The present disclosure relates to a small object detection method and apparatus, a readable storage medium, and an electronic device. The method includes: inputting a to-be-detected image to a pre-trained small object detection model; and separately encoding and decoding information of the to-be-detected image in the small object detection model using a desubpixel convolution operation and a subpixel convolution operation running in pair: and extracting features in the to-be-detected image through the small object detection model, and outputting an object's category and location in the to-be-detected image. The present disclosure aims at solving the technical problem in the prior art that traditional FPNs fail to consider the correlation between the downsampling in the backbone network and the upsampling in the neck network during feature fusion, which leads to redundant operations and information loss.

  • Patent number: 5656422
    Abstract: Methods and compositions are provided for the detection of 2,4-dichlorophenoxyacetic acid (2,4-D) and other phenoxy ether compounds. The phenoxy ether bond of 2,4-D is enzymatically cleaved by 2,4-D .alpha.-ketoglutarate dioxygenase to form 2,4-dichlorophenol, which is assayed by the 4-aminoantipyrine method. The enzyme is supplied in a dried form, preferably immobilized on a solid support, and is stable at room temperature for several months even in a highly impure state, e.g., crude cell extracts or dried cells.
