如何将CRFAsRNN移植到caffe-windows上去

（1）移植辅助的文件
将include/caffe/util/下的coords.hpp和modified_permutohedral.hpp复制到caffe-windows对应的目录将src/caffe/util/modified_permutohedral.cpp复制到对应的目录中去

（2）移植Layer中的特性
在include/caffe/layer.hpp中添加如下代码：#include "caffe/util/coords.hpp"
和以下代码： virtual DiagonalAffineMap coord_map() { NOT_IMPLEMENTED; // suppress warnings return DiagonalAffineMap(vector >()); }修改后的文件如下：#ifndef CAFFE_LAYER_H_#define CAFFE_LAYER_H_
#include #include #include
#include "caffe/blob.hpp"#include "caffe/common.hpp"#include "caffe/layer_factory.hpp"#include "caffe/proto/caffe.pb.h"#include "caffe/util/coords.hpp"#include "caffe/util/math_functions.hpp"
