我正在尝试计算两个图像之间的互信息，为此我使用了“MutualInformationImageToImageMetric”类。阅读此示例后：http ://www.itk.org/Wiki/ITK/Examples/Registration/MutualInformation我在我的代码中使用了以下四个新的“#include”行：
#include "itkImageRegistrationMethod.h"
#include "itkTranslationTransform.h"
#include "itkMutualInformationImageToImageMetric.h"
#include "itkLinearInterpolateImageFunction.h"
之后我收到一个致命错误，告诉我：'itkSingleValuedCostFunction.h'：没有这样的文件或目录
我已经使用了很多其他类别的 itk，而且它总是有效……现在发生了什么？请问有什么提示吗？
谢谢 ！

I'm using the GIT version of ITK and updated my CMakeList.txt to
cmake_minimum_required(VERSION 2.8)
PROJECT(MutualInformation)
FIND_PACKAGE(ITK REQUIRED)
INCLUDE(${ITK_USE_FILE})
ADD_EXECUTABLE(MutualInformation MutualInformation.cxx)
TARGET_LINK_LIBRARIES(MutualInformation ${ITK_LIBRARIES})
Everything went fine.
Which ITK have you built? I do not have ITK 3.20 built right now. Does itkSingleValuedCostFunction.h exist under Code\Numerics ? Is you makefile properly set to TARGET_LINK_LIBRARIES(MutualInformation ITKIO ITKNumerics) ? Or, if you use ITK git, do you see the file under Modules\Numerics\Optimizers\include ?
Note that you could post questions related to ITK on the ITK mailing list. Register at http://www.itk.org/mailman/listinfo/insight-users
