Web1 apr. 2024 · Libra R-CNN [17] constructs a histogram based on IoU for negative examples and selects examples from each bin in the histogram uniformly as hard negative examples. Different from these strategies, IoU-balanced loss functions don’t change the sampling process and only adaptively assign different weights to the positive examples based on … Web11 dec. 2024 · Figure 1 (a) shows the IoU histogram of the Region of interests (RoIs) generated by the RPN. With the increase of IoU, the number of RoIs decreases sharply, leading to the IoU distribution imbalance. As the subsequent R-CNN takes the RoIs as training samples, the distribution of training samples is naturally skewed towards lower …
