Mustard convolutionGeneralised convolutionRecently the construction of various integral transforms for slice monogenic functions has gained a lot of attention. In line with these developments, the article at hand introduces the slice Fourier transform. In the first part, the kernel function of this ...

The LACs were segmented in four conditions, two slice thicknesses (Thin: 1mm; Thick: 5mm) and two convolution kernels (Sharp: B70f/B70s; Smooth: B30f/B31f/B31s), which constituted four groups: (1) Thin-Sharp, (2) Thin-Smooth, (3) Thick-Sharp, and (4) Thick-Smooth. Machine ...

where * is a convolution operator, B denotes blurry kernel which is general an isotropic Gaussian kernel with a given σ (say 0.8), and ↓s presents subsampling with a scaling factor s. Ih and Il are initial SEM image as well as its degraded versions, respectively. Low-resolution µ-CT...
其中,encoder由堆叠的convolution module构成,decoder由堆叠的convolution module+attention module构成。 6.1 卷积模块 每一个Convolution step由三个部分组成:对输入x的relu激活,跟着一个Depthwise separable convolution操作SepConv,在跟着一个layer Normalization。(关于layer Normalization详细介绍,参考文章《<优化策略-2>深度...
3a, in spatial CNN, one slice only receives the feature from its upper slice by directly utilizing convolution operation. For the complicated tree-like airway structure, there are several limitations in spatial CNN: (1) insufficient feature propagation. Some breakages in the airway are dependent ...
Both blocks use a sequence of multiple 1 × 1 convolution lay- ers to produce independent feature representations for each point. 3.2. Local Dependency Module The key part of an RSNet is the local dependency mod- ule which is a combination of a slice pooling layer, RNN layers, and a ...
To emphasize this point: if FF were independent of pp, then one could use the convolution theorem to Fourier transform back into position space where you will find a convenient δδ-function that forces Φ(p)Φ(p) and Φ(−p)Φ(−p) to be evaluated at the same spacetime p...
