S3Pool: Pooling with Stochastic Spatial Sampling CVPR2017https://github.com/Shuangfei/s3pool 本文将常规池化看作两个步骤: 1)以步长为1在特征图上滑动池化窗口,尺寸大小基本保持不变, leaves the spatial resolution intact 2)以一种 uniform 和
stochastic pooling方法非常简单,只需对feature map中的元素按照其概率值大小随机选择,即元素值大的被选中的概率也大.而不像max-pooling那样,永远只取那个SPP(Spatial Pyramid Pooling)详解 一直对Fast RCNN中ROI Pooling层不解,不同大小的窗口输入怎么样才能得到同样大小的窗口输出呢,今天看到一篇博文讲得挺好的,摘录...
Max Pooling:区域最大值。 Stochastic Pooling:它使用一个核区域内激活的概率加权抽样。 Mix Pooling:基于最大池化和平均池化的混合池化。 Power average Pooling:基于平均和最大化的结合,幂平均(Lp)池化利用一个学习参数p来确定这两种方法的相对重要性;当p=1时,使用局部求和,而p为无穷大时,对应max-pooling。 网...

Max pooling and average pooling represent the primary downsampling techniques extensively utilized in various segmentation architectures, including UNet [5] and PSPNet [9]. Adaptive pooling [33] has also been explored in various studies, with examples including stochastic pooling [34] by replacing the...
Apart from the common down-sampling operations for feature aggregation in CNNs (usually applied by max, mean, or stochastic pooling layers), deep learning-based image segmentation models are also equipped with up-sampling for feature map recovery. As shown in Fig. 4., down-sampling is similar...

Downsampling can be implemented by indexing out the appropriate elements or using any windowed operation (such as maximum or average pooling) with a stride larger than one. This operation can also be approximated by: Ii,j(t + 1) = Ii,j(t) + hS max (max(Ik,...
