1. ResNet and DenseNet
ResNet (Deep Residual Network): By establishing a "short-circuit connection" between the front and back layers, this helps to reverse the propagation of gradients during training, resulting in a deeper CNN network.
DenseNet: uses a dense join mechanism, where all layers are connected to each other, a ...

In order to enhance semantics, the traditional object detection model usually only carries out subsequent operations on the last feature map of the deep convolution network, and the down sampling rate (multiple of image reduction) corresponding to this layer is usually large, ...

Among the trained image target detection provided by Pytorch, they are R-CNN series networks, and provide easy to call methods for target detection and human key point detection respectively. For the network of target detection, the input images are required to use the same preprocessing method, that is, the pixel value of each image is preproc ...

Reference code: YOLOF
Introduction: review the FPN network commonly used in previous detection networks to fuse features of different scales and detect targets under different scales (targets of different sizes will be assigned to FPN feature maps of different stripes). This is actually a divide and conquer strategy. However, su ...

Before learning, I always looked at CSDN and knowledge, but I still felt that many details were not well understood, so I recently planned to start reading the original text and record my ideas and code analysis.
There may be some typos or wrong conclusions. I hope you will forgive me.
The current top target detection netw ...

Non maximum suppression prediction bounding box
When there are many anchor boxes, many similar prediction bounding boxes with obvious re bands may be output. Around the same target, in order to simplify the output, use non maximum suppression (NMS) to merge similar prediction bounding boxes c ...
