Description

tried to build the java wrappers, but anything, that returns a cv::Ptr<>
gets "skipped".

calib3d.txt:

Ptr_StereoBM createStereoBM(int numDisparities = 0, int blockSize = 21)
// Return type 'Ptr_StereoBM' is not supported, skipping the function
Ptr_StereoSGBM createStereoSGBM(int minDisparity, int numDisparities, int blockSize, int P1 = 0, int P2 = 0, int disp12MaxDiff = 0, int preFilterCap = 0, int uniquenessRatio = 0, int speckleWindowSize = 0, int speckleRange = 0, int mode = StereoSGBM::MODE_SGBM)
// Return type 'Ptr_StereoSGBM' is not supported, skipping the function

contrib.txt:

Ptr_FaceRecognizer createEigenFaceRecognizer(int num_components = 0, double threshold = DBL_MAX)
// Return type 'Ptr_FaceRecognizer' is not supported, skipping the function
Ptr_FaceRecognizer createFisherFaceRecognizer(int num_components = 0, double threshold = DBL_MAX)
// Return type 'Ptr_FaceRecognizer' is not supported, skipping the function
Ptr_FaceRecognizer createLBPHFaceRecognizer(int radius = 1, int neighbors = 8, int grid_x = 8, int grid_y = 8, double threshold = DBL_MAX)
// Return type 'Ptr_FaceRecognizer' is not supported, skipping the function

video.txt:

Ptr_BackgroundSubtractorGMG createBackgroundSubtractorGMG(int initializationFrames = 120, double decisionThreshold = 0.8)
// Return type 'Ptr_BackgroundSubtractorGMG' is not supported, skipping the function
Ptr_BackgroundSubtractorMOG createBackgroundSubtractorMOG(int history = 200, int nmixtures = 5, double backgroundRatio = 0.7, double noiseSigma = 0)
// Return type 'Ptr_BackgroundSubtractorMOG' is not supported, skipping the function
Ptr_BackgroundSubtractorMOG2 createBackgroundSubtractorMOG2(int history = 500, double varThreshold = 16, bool detectShadows = true)
// Return type 'Ptr_BackgroundSubtractorMOG2' is not supported, skipping the function

this probably explains other issues people noticed before,
