针对《图像语义分割（1）- FCN》介绍的FCN算法，以官方的代码为基础，在 SIFT-Flow 数据集上做训练和测试。
介绍了如何制作自己的训练数据
数据准备
参考文章《FCN网络的训练——以SIFT-Flow 数据集为例》
1） 首先 clone 官方工程
git clone https://github.com/shelhamer/fcn.berkeleyvision.org.git- 1
工程是基于 CAFFE 的，所以也需要提前安装好
2）下载数据集及模型
- 到这里下载 SIFT-Flow 数据集，解压缩到 fcn/data/sift-flow/ 下
- 到这里下载 VGG-16 预训练模型，移动到 fcn/ilsvrc-nets/ 下
- 参考文章《 FCN模型训练中遇到的困难》，到这里下载 VGG_ILSVRC_16_layers_deploy.prototxt
或者直接 copy 以下内容：
