Slice Layer

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).
