Slice Layer

Layer type: Slice
Doxygen Documentation
Header: ./include/caffe/layers/slice_layer.hpp
CPU implementation: ./src/caffe/layers/slice_layer.cpp
CUDA GPU implementation: ./src/caffe/layers/slice_layer.cu

The Slice layer is a utility layer that slices an input layer to multiple output layers along a given dimension (currently num or channel only) with given slice indices.

Sample

layer {
  name: "slicer_label"
  type: "Slice"
  bottom: "label"
  ## Example of label with a shape N x 3 x 1 x 1
  top: "label1"
  top: "label2"
  top: "label3"
  slice_param {
    axis: 1
    slice_point: 1
    slice_point: 2
  }
}

axis indicates the target axis; slice_point indicates indexes in the selected dimension (the number of indices must be equal to the number of top blobs minus one).
