caffe::Im2colLayer::LayerSetUp
virtual void LayerSetUp(const vector< Blob< Dtype > * > &bottom, const vector< Blob< Dtype > * > &top)
Does layer-specific setup: your layer should implement this function as well as Reshape.
Definition: im2col_layer.cpp:9
caffe::Im2colLayer::pad_
Blob< int > pad_
The spatial dimensions of the padding.
Definition: im2col_layer.hpp:48
caffe::Im2colLayer::Reshape
virtual void Reshape(const vector< Blob< Dtype > * > &bottom, const vector< Blob< Dtype > * > &top)
Adjust the shapes of top blobs and internal buffers to accommodate the shapes of the bottom blobs.
Definition: im2col_layer.cpp:107
