(NAS) methods that typically searched the optimal operators in each network layer, but missed a good strategy to search for feature aggregations, this paper proposes a novel NAS method for 3D medical image segmentation, named UXNet, which searches both the scale-wise feature aggregation strategies...
the paper proposes a Multi-level Feature Aggregation Network (MFANet), which is improved in two aspects: deep feature extraction and up-sampling feature fusion. Firstly, the proposed Channel Feature Compression module extracts the deep features and filters the redundant channel information from the ba...
所以提出M2Det模型,主要是Multi-Level Feature Pyramid Network(MLFPN)模块,其由Thinned U-shape Modules(TUM),Feature Fusion Modules(FFM)和Scale-wise Feature Aggregation Module(SFAM)组成,可以看出本文的工作量肯定不小。 2 相关模型 如下图所示,文中列举了四种风格的特征金字塔:SSD型、FPN型、STDN型,以及本...
如Figure 2所示,我们首先将backbone提取的多级特征(即多层)融合为基础特征,然后将其输入Multi-Level Feature Pyramid Network(MLFPN)中。MLFPN包含交替连接的Thinned U-shape Modules(TUM)、Feature Fusion Module(FFM)和Scale-wise Feature Aggregation Module (SFAM)。其中,TUMs和FFMs提取出更具代表性的多级多尺度特征。

2. First, we present a Feature Aggregation Network (FAN, Section 3.1) to extract multilevel CNN features for the input image pairs. Then, the paired CNN features are forward into Recurrent Comparative Network (RCN, Section 3.2) to learn joint representation of two images for verification task,...
iii. Scale-wise Feature Aggregation Modules(SFAM) -- 多尺度特征融合 3.解码层(decorder layer) 形成的最终特征金字塔要比backbone层还要深。 FFMv1,通过融合主干(backbone)特征映射,将语义信息丰富成基本特征(base feature)。 TUM, 每一个TUM会生成一组多尺度特征,然后利用多级交流节点TUMs和FFMv2s提取多级多尺...
其中FFMv1(Feature Fusion Module)用于混合由backbone提取的多层级特征作为基础特征;TUMs(Thinned U-shape Modules)以及FFMv2s通过基础特征提取出多层级多尺度的特征;SFAM(Scale-wise Feature Aggregation Module)将这些多层级多尺度特征依据相同尺度进行整合得到最终的特征金字塔。基于MLFPN的M2Det是一个高效的end-to-...
