RPN architecture and its PyTorch implementation

introduction because RPN architecture RPN Generation method of AnchorHow to select anchor as proposalsFor loss calculation, you need to select positive and negative samples from anchor before calculating loss In fact, RPN itself can be used as the Head of target detection Anchor generation So how did proposal come into being? It is ...

Two irregular quadrilateral IOU calculation methods

1 Introduction Our common target detection is rectangular box detection, but sometimes the box we detect is an irregular quadrilateral. The following figure is a common remote sensing image. At this time, the way we use rectangular box to calculate IOU is no longer applicable. We can abstract the problem. Is there a way to calculate two irregu ...

Reproducing pointrcnn + Ubuntu 16.043080 graphics card + pytorch1.7.1+cu110

Reproduce pointrcnn          In the process of reproducing pointrcnn, the easiest place to report errors is to compile CUDA code. Most of the issue s of github emphasize the version problems of gcc and pytorch, but I use 3080 graphics card, which only supports > = cuda11.0, so installing a lower versi ...

YOLOv5 data augmentation

1. Introduction to data enhancement When there are few pictures in our training set, it is easy to cause over fitting of the network. In order to avoid this situation, we generally need to increase some picture data artificially through image processing, which will increase the number of available pictures and reduce the possibility of over ...
