WebThe IoU-balanced sampling can guide the distribution of training samples close to the one of hard negatives. **IoU-Balanced Sampling** is hard mining method for object … Webpling heuristics [3, 19, 22]; (2) non-sampling schemes, con-sisting of ranking-based loss functions [6, 27] and unbiased learning mechanisms [4, 5]. In this section, we will describe these solutions in detail. 3.1. Sampling Heuristics In essence, sampling heuristics addresses the imbalance by changing the contribution of each example e.g. put more
Libra R-CNN: Towards Balanced Learning for Object Detection
Web6 aug. 2024 · (a) Given an untrimmed video containing several action instances of small scale, (b) IoU-balanced sampling is widely used to train the proposal confidence regressor, which still suffers from inferior quality owing to the imbalanced distribution of the tem- poral durations, resulting in the long-tailed proposal dataset. Web28 okt. 2024 · Abstract: Detecting objects in aerial images usually faces two major challenges: (1) detecting difficult targets (e.g., small objects, objects that are interfered by the background, or various orientation of the objects, etc.); (2) the imbalance problem inherent in object detection (e.g., imbalanced quantity in different categories, imbalanced … inc a business
