WebAug 28, 2024 · 卷积层(conv) 卷积,尤其是图像的卷积,需要一个滤波器,用滤波器对整个图像进行遍历,我们假设有一个32*32*3的原始图像a,滤波器的尺寸为5*5*3,用w表示,滤波器中的数据就是cnn的参数的一部分,那么在使用滤波器w对a进行滤波的话,可以用下面的式子表示: WebConv3D class. 3D convolution layer (e.g. spatial convolution over volumes). This layer creates a convolution kernel that is convolved with the layer input to produce a tensor of outputs. If use_bias is True, a bias vector is created and added to the outputs. Finally, if activation is not None, it is applied to the outputs as well.
