**

一 添加新的caffe layer

**
需要添加的层有两个 UpsampleLayer 和 BNLayer.
Upsample 是对图像进行放大使用的，功能可类比于 Deconv层。
BN 就是BatchNorm ,caffe官方也有实现，这里最好用作者的，省得再去改网络参数。
这里给出两个层的cpp hpp cu 文件。
除此之外，还要修改caffe.proto文件，声明这两个层。

二 修改SegNet数据输入层

原来的数据输入层，为此作者还新加了DenseImageDataLayer.其实没必要用这个层。

layer {
  name: "data"
  type: "DenseImageData"
  top: "data"
  top: "label"
  dense_image_data_param {
    source: "/SegNet/CamVid/train.txt"	# Change this to the absolute path to your data file
    batch_size: 4   			# Change this number to a batch size that will fit on your GPU
    shuffle: true
  }
}

数据输入层写为下面的样式。将data label 分别输入。

layer {
  name: "data"
  type: "Data"
  top:"data"
  include {
    phase: TRAIN
  }
  transform_param {
mean_file: "G:/interest_of_imags_for_recognation/VOC2012/Resize224/Img_train_mean.binaryproto"
  }
  data_param {
    source: "G:/interest_of_imags_for_recognation/VOC2012/Resize224/Img_train"
    batch_size: 1
    backend: LMDB
  }
}
layer {
  name: "label"
  type: "Data"
  top:"label"
  include {
    phase: TRAIN
  }
  data_param {
    source: "G:/interest_of_imags_for_recognation/VOC2012/Resize224/Label_train"
    batch_size: 1
    backend: LMDB
  }
}
layer {
  name: "data"
  type: "Data"
  top: "data"
  include {
    phase: TEST
  }
  transform_param {
	mean_file: "G:/interest_of_imags_for_recognation/VOC2012/Resize224/Img_val_mean.binaryproto"
  }
  data_param {
    source: "G:/interest_of_imags_for_recognation/VOC2012/Resize224/Img_val"
    batch_size: 1
    backend: LMDB
  }
}
layer {
  name: "label"
  type: "Data"
  top: "label"
  include {
    phase: TEST
  }
  data_param {
    source: "G:/interest_of_imags_for_recognation/VOC2012/Resize224/Label_val"
    batch_size: 1
    backend: LMDB
  }
