The network structure can be divided into three parts: Backbone, Neck and Head. Backbone network is the main part of the model and is responsible for the feature extraction of the input feature map. It mainly consists of Conv-BN-LeaklyRELU (CBL), ELAN and Maximum Pooling (MP) modules. ...
ELAN ( Efficient Layer Aggregation Networks ) is mainly composed of VoVNet combined with CSPNet, and optimizes the gradient length of the overall network with the structure of stack in computational block. ELAN 针对的问题是在 model scaling 中模型表现变差的问题。
In 2016, Redmon J9 proposed the YOLOv1 algorithm with a single Network structure, which transformed the target detection task into a regression problem. By dividing the input image into multiple grids, each grid was used to identify the category and boundary box of the predicted target. ...
Faster-YOLOv7 is proposed.By using the contrast limited adaptive histogram equalization (CLAHE) with limited contrast for image enhancement, the contrast of foreign objects in low light environments is improved. Lightweight design of the YOLOv7 backbone network ...
Now, it’s time to set up our options for training the network. We will make use of various flags to do so, including: img-size: This parameter corresponds to the size of the image in pixels. For YOLOv7, The image must be square one. To make it so, the original image is resized...
The test results and ablation experiments on the KITTI public dataset show that compared with the benchmark network, the inference time of cascade YOLOv7 model is shortened by 40 ms?frame-1, with the mean average precision of detection at the moderate, difficulty level increased by 8.77%, ...
