作者称是第一篇将 Transformer 结构用于 Geo-localization 任务的文章,其实这个也就是应用一下,但有趣的创新点在于作者提出了层间的 Attention 机制。 整体结构如上图,其实很简单,两个分支结构一样,由一个 CNN 特征提取骨架网络和一个编码器组成。输入时会加上一维的位置编码,由于是地形图,拍摄角度与广度都与分类...
2. 交叉视角的 cross-attention机制 这部分主要是实现了感知相机的位置编码,利用相机独立的校准矩阵(内外参等)对特征进行位置编码。这部分也是论文的核心,利用注意力机制进行处理。在lift、fiery是用深度估计概率编码(卷积的方法)。下面公式是位置编码时候世界相对坐标和图像坐标的处理。 3.设计一个轻量级的解码网络decod...
We present a novel cross-view attention module (CvAM) which implicitly learns to focus on the cancer-related local abnormal regions and highlighting salient features by exploring cross-view information among four views of a screening mammography exam, e.g. asymmetries between left and right breasts...
在PanFusion这篇论文中,全景分支(Panorama Branch)和透视分支(Perspective Branch)之间的信息传递是通过一个称为Equirectangular-Perspective Projection Attention (EPPA) 模块来实现的。这个模块包括两个关键部分:EPP球面位置编码(EPP Spherical Positional Encoding)和EPP注意力掩码(EPP Attention Mask)。 1. EPP球面位置...

Attention 我们还利用注意力来实现SP。我们在我们的工作中包含了两种注意策略。 第一种是像素级注意力。具体而言,我们通过利用全局信息来细化SP的输出,学习每个帧级特征图的逐元素注意力映射,如图b所示。首先,全局信息通过统计函数进行收集。然后,它与原始特征图一起输入到1×1卷积层中,以计算细化的注意力映射。最终...

Therefore, aiming at the information interaction and stereo consistency of stereo image pairs, a cross-view attention interaction fusion stereo super-resolution algorithm is proposed. Firstly, based on parallax attention mechanism and triple attention mechanism, an attention stereo fusion module is ...
