Upsample、ConvTranspose2d、conv后PixelShuffle用法上有什么区别? 不改变特征图通道数而将特征图尺寸扩大一倍有3个方法: 1.Upsample上采样 2.先用卷积将通道数扩大一倍,然后用PixelShuffle,将两个通道的特征图相互插入使得尺寸扩大一倍。 3.利用反卷积ConvTranspose2d不改变通道数尺寸扩大一倍。 请问三者有什么区别呢?...
去年曾经使用过FCN(全卷积神经网络)及其派生Unet,再加上在爱奇艺的时候做过一些超分辨率重建的内容,其中用到了毕业于帝国理工的华人博士Shi Wenzhe(在Twitter任职)发表的PixelShuffle《Real-Time Single Image and Video Super-Resolution Using an Efficient Sub-Pixel Convolutional Neural Network》的论文。 PyTorch 0.4...
【CV基础】几种上采样方法(upsample/unpool/convtranspose/pixelshuffle)的理解,参考1. pytorch中的上采样(上采样,转置卷积,上池化,PixelShuffle);完
上采样通常有四种方式: upsample / Interpolation unpooling deconvolution / transpose convolution pixel shuffle / sub-pixel convolution 反卷积/转置卷积:原理上是转置、逆变换,形式上是先padding再卷积,使得输出分辨率变大:https://github.com/vdumoulin/conv_arithmetic、https://blog.csdn.net/qq_16234613/article...
