Modification

• In opencv/modules/calib3d/CMakeLists.txt, opencv/modules/features2d/CMakeLists.txt and opencv_contrib/modules/aruco/CMakeLists.txt

  Add "js" parameter in ocv_define_module

• In opencv/modules/js/src/core_bindings.cpp, add

  Add:

  \#include "opencv2/aruco.hpp"
  \#include "opencv2/calib3d.hpp"
  \#include "opencv2/features2d.hpp"
  using namespace cv::aruco;

• In opencv/modules/js/src/embindgen.py

  Add:

  aruco = {'': ['drawMarker', 'detectMarkers', 'drawDetectedMarkers', 'estimatePoseSingleMarkers', 'drawAxis'],
          'Dictionary': ['Dictionary', 'create', 'get', 'getPredefinedDictionary'],
          'DetectorParameters': ['DetectorParameters', 'create']}

  Modify:

  white_list = makeWhiteList([core, imgproc, objdetect, video, dnn]) -> white_list = makeWhiteList([core, imgproc, objdetect, video, aruco])
  return re.sub(r"^cv\.", "", name).replace(".", "_") -> return re.sub(r"^cv\.[a-zA-Z0-9]*\.|cv\.", "", name).replace(".", "_")

• In opencv/platforms/js/build_js.py

  Add:

  "-DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules",

  Modify:

  "-DBUILD_opencv_calib3d=off" -> "-DBUILD_opencv_calib3d=on"
  "-DBUILD_opencv_features2d=off" -> "-DBUILD_opencv_features2d=on"

• In opencv/modules/imgproc/include/opencv2/imgproc.hpp
