论文摘要
我们提出Osformer，这是第一个用于伪装实例分割（CIS）的单阶段变压器框架。 Osformer基于两个关键设计。首先，我们设计了一个位置传感变压器（LST），以通过引入位置引导的查询和混合通风volvolution Feedforward网络来获得位置标签和实例感知参数。其次，我们开发了一个粗到细节的融合（CFF），以合并LST编码器和CNN骨架的各种上下文信息。结合这两个组件使Osformer能够有效地融合本地特征和远程上下文依赖关系，以预测伪装的实例。与两阶段的框架相比，我们的OSFORMER达到41％的AP并达到良好的收敛效率，而无需大量的训练数据，即仅3040个以下的样本以下60个时代。代码链接：https：//github.com/pjlallen/osformer。
We present OSFormer, the first one-stage transformer framework for camouflaged instance segmentation (CIS). OSFormer is based on two key designs. First, we design a location-sensing transformer (LST) to obtain the location label and instance-aware parameters by introducing the location-guided queries and the blend-convolution feedforward network. Second, we develop a coarse-to-fine fusion (CFF) to merge diverse context information from the LST encoder and CNN backbone. Coupling these two components enables OSFormer to efficiently blend local features and long-range context dependencies for predicting camouflaged instances. Compared with two-stage frameworks, our OSFormer reaches 41% AP and achieves good convergence efficiency without requiring enormous training data, i.e., only 3,040 samples under 60 epochs.
