但传统的孪生网络并未提取目标较深层特征来保持泛化性能,并且大多数孪生网络只提取局部领域特征,这使得模型对于外观变化是非鲁棒和局部的。 |
However, the traditional siamesenetwork does not extract the deeper features of the target to maintain generalization performance, and mostsiamese architecture networks usually process one local neighborhood at a time, which makes the appearancemodel local and non-robust to appearance changes. |
