Question

我想知道如何在macOS Sierra上编译opencv_traincascade程序。

我有traincascade的源代码（在文件夹/opencv-2.4.13/apps/traincascade/中）。但是，当我转到此文件夹并在终端上输入时：

cmake ..

它返回：

=＆GT;它不理解“ocv_check_dependencies”

这是CMakeLists.txt代码：

SET(OPENCV_TRAINCASCADE_DEPS opencv_core opencv_ml opencv_imgproc opencv_objdetect opencv_highgui opencv_calib3d opencv_video opencv_features2d opencv_flann opencv_legacy)
ocv_check_dependencies(${OPENCV_TRAINCASCADE_DEPS})

if(NOT OCV_DEPENDENCIES_FOUND)
  return()
endif()

project(traincascade)

ocv_include_directories("${CMAKE_CURRENT_SOURCE_DIR}" "${OpenCV_SOURCE_DIR}/include/opencv")
ocv_include_modules(${OPENCV_TRAINCASCADE_DEPS})

set(traincascade_files traincascade.cpp
  cascadeclassifier.cpp cascadeclassifier.h
  boost.cpp boost.h features.cpp traincascade_features.h
  haarfeatures.cpp haarfeatures.h
  lbpfeatures.cpp lbpfeatures.h
  HOGfeatures.cpp HOGfeatures.h
  imagestorage.cpp imagestorage.h)

set(the_target opencv_traincascade)
add_executable(${the_target} ${traincascade_files})
target_link_libraries(${the_target} ${OPENCV_TRAINCASCADE_DEPS} opencv_haartraining_engine)

set_target_properties(${the_target} PROPERTIES
                      DEBUG_POSTFIX "${OPENCV_DEBUG_POSTFIX}"
                      ARCHIVE_OUTPUT_DIRECTORY ${LIBRARY_OUTPUT_PATH}
                      RUNTIME_OUTPUT_DIRECTORY ${EXECUTABLE_OUTPUT_PATH}
                      OUTPUT_NAME "opencv_traincascade")

if(ENABLE_SOLUTION_FOLDERS)
  set_target_properties(${the_target} PROPERTIES FOLDER "applications")
endif()

if(INSTALL_CREATE_DISTRIB)
  if(BUILD_SHARED_LIBS)
    install(TARGETS ${the_target} RUNTIME DESTINATION ${OPENCV_BIN_INSTALL_PATH} CONFIGURATIONS Release COMPONENT dev)
  endif()
else()
  install(TARGETS ${the_target} RUNTIME DESTINATION ${OPENCV_BIN_INSTALL_PATH} COMPONENT dev)
endif()

此外，这个问题引起了我的注意，因为我在训练过程中遇到了-featureType LBP。当我使用LBP功能训练我的面部检测器时，它显示：

Andy-Chen:Temp Training macpro$ opencv_traincascade -data data -vec faces_15000-80000.vec -bg neg.txt -numPos 4000 -numNeg 10000 -numStages 10 -w 21 -h 24 -featureType LBP
===== TRAINING 0-stage =====
<BEGIN
POS count : consumed   4000 : 4000
NEG count : acceptanceRatio    10000 : 1

然后它保持这个状态几个小时没有任何进展。但是，如果我使用HAAR功能进行训练，一切正常。

因此，我想在traincascade的源代码中添加一些“cout”命令，以便我可以看到程序被卡住的位置，然后寻找解决方案或修改某些内容以使其可行。

我期待着您的帮助。非常感谢您的宝贵时间。
