WebApr 1, 2024 · Abstract. We propose an anchor-free object detector that combines a weighted bi-directional Feature Pyramid Network (BiFPN) and Soft Detector to address the object detection problem in a pixel-wise paradigm. The current mainstream object detection methods are anchor-based, which require to set hyper parameters such as scale and … WebPedestrian detection based on visual sensors has made significant progress, in which region proposal is the key step. There are two mainstream methods to generate region proposals: anchor-based and anchor-free. However, anchor-based methods need more hyperparameters related to anchors for training compared with anchor-free methods. In …

RepPoints (anchor-free) You can see that YOLOv4 can be implemented in any combination of input, backbone ... Let F_i\in \mathbb {R}^{H/s_i\times W/s_i\times C_i} be the i-th layer of feature map of CNN and s_i is the corresponding stride of the feature map. (H, W) is the size of input image, and C_i denotes the number of channels of i-th layer of feature map. A ground truth bounding box is defined as b_i, where … See more Before FPN [22], most detectors tend to use only the deepest feature map to do detection, while the feature map with high level semantics may lose many details and cannot accurately … See more Here, we provide (Fig. 4) for a visualization of our network architecture.
