Introduced by Xiang Long et al. in PP-YOLO: An Effective and Efficient Implementation of Object Detector
archive 2025-07-28 Description, source and code snippet are the archive's method entry.
PP-YOLO is an object detector based on YOLOv3. It mainly tries to combine various existing tricks that almost not increase the number of model parameters and FLOPs, to achieve the goal of improving the accuracy of detector as much as possible while ensuring that the speed is almost unchanged. Some of these changes include:
- Changing the DarkNet-53 backbone with ResNet50-vd. Some of the convolutional layers in ResNet50-vd are also replaced with deformable convolutional layers.
- A larger batch size is used - changing from 64 to 192.
- An exponentially moving average is used for the parameters.
- DropBlock is applied to the FPN.
- An IoU loss is used.
- An IoU prediction branch is added to measure the accuracy of localization.
- Grid Sensitive is used, similar to YOLOv4.
- Matrix NMS is used.
- CoordConv is used for the FPN, replacing the 1x1 convolution layer, and also the first convolution layer in the detection head.
- Spatial Pyramid Pooling is used for the top feature map.

Tasks archive 2025-07-28
9 tasks the archive attaches to papers tagged with this method, by distinct papers. A task without a page in the catalog is plain text.
Usage over time archive 2025-07-28
Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
