Specifically, to deal with the instance matching problem in the dynamic clutter situations, an instance-wise contrastive loss is introduced to make all the same instances to be near together, …
Nettet18. jan. 2024 · IOU is defined as follows: IOU = true_positive / (true_positive + false_positive + false_negative). The predictions are accumulated in a confusion matrix, weighted by `sample_weight` and the metric is then calculated from it. If `sample_weight` is `None`, weights default to 1. Use `sample_weight` of 0 to mask values. Nettetization of the calculated instance-wise IoU of prediction and ground truth. Green color corresponds to high IoU values. Bottom right : Depth estimation map. work, a score threshold is applied to remove all instances with low condences. This is done to balance the number of false positive and false negative instances. Nevertheless, this can
