  • Freeanchor: abandon single IOU matching, more free anchor matching method šž“œ nips 2019

    Timeļ¼š2020-6-3

    This paper abandons the previous method of assigning anchor and gt matching relationship according to the rigidity of IOU, and proposes freeanchor method to match more freely. This method defines the training of target detection as the maximum likelihood estimation (MLE) process, and simultaneously learns target classification, target detection and matching relationship from end to […]

  • Evaluation index of machine learning algorithm — 2D target detection

    Timeļ¼š2020-6-2

    Target detection is a traditional task in the field of computer vision. It is necessary to identify the object on the image, give the corresponding category, and give the position of the object through the way of minimum bounding box. The following describes the common evaluation indicators of 2D target detection tasks. IoUļ¼ˆIntersection over Unionļ¼‰ […]

  • Neurips 2019 | small sample target detection based on CO attention and co exception

    Timeļ¼š2020-5-16

    In this paper, the COAE small sample target detection algorithm is proposed. The algorithm uses non local block to extract the corresponding features between the target image and the query image, so that the RPN network can accurately obtain the location of the corresponding category of objects. In addition, the se block like squeeze and […]
