foreground probability is calculated based on the target image of a single sample image; foreground probability calculation target image; configuration Gibbs energy minimization and by solving FIG dividing each pixel corresponding to the foreground or background The results of the constructed Gibbs energy...
Hierarchical Point set feature learning 由一系列点集抽象层(set abstraction)组成,而每一个set abstraction 又由三个关键层组成:sampling layer,Grouping layer,PointNet Layer。 Sampling layer:Sampling layer的作用是从点云中选择很多个质点和围绕在这些质点的局部区域。 作为输入,通过使用FPS算法(farthest point ...
Understanding Convolution for Semantic Segmentation Abstract 首先,我们设计了密集卷积上采样(dense upssampling convolution DUC)可以获得像素级别的上采样,DUC可以获取并解码一些细节信息,这些细节信息是双线性插值上采样不能获取的。第二,在编码部分我们提出了混合空洞卷积(Hybrid... ...

While these deep learning-based segmentation algorithms have improved the accuracy of retinal vessel segmentation to some extent, they face challenges when dealing with fine vessels and subtle differences between vessel boundaries and background pixels. This can lead to feature information loss during the...
Segmentation of structures is accomplished with Full Convolutional neural networks that help recover spatial information lost during the sub-sampling of CNNs. The current approach and studies made here are summarized as follows,. Jia et al. [117] suggested a CNN-based two-stage architecture called...

Each RefineNet block has a component to fuse the multi resolution features by upsampling the lower resolution features and a component to capture context based on repeated 5 x 5 stride 1 pool layers. Each of these components employ the residual connection design following the identity map mindset....
I am searching an alternative based on this one. The main idea comes from LSTM's attention mechanism. I use separated convolutions on input image and binary mask. The binary mask has 1 for valid pixel and 0 for hole. By reversing the label, its convolution outputs have 0 on all valid ...
