adaptiveThreshold is not covered with accuracy tests about opencv HOT 6 OPEN

Yes @Octopus136 .

from opencv.

@asmorkalov Sir, I would like to work on writing tests for adaptive threshold but when I went about understanding everything about it, I am bit lost. Can you guide me on how to write tests for adaptiveThreshold.

@Dhanwanth1803 Hi, have you started working on it? I also have some thoughts about writing this test.

from opencv.

@asmorkalov @dkurt Sir, I need help.

In addition to accuracy tests for adaptiveThreshold. I didn't find any test corresponding to
void cv::adaptiveThreshold( InputArray _src, OutputArray _dst, double maxValue, int method, int type, int blockSize, double delta ) from /opencv/modules/imgproc/src/thresh.cpp

So my doubt is should I go about writing a function named void test_threshold(...) in /opencv/modules/imgproc/test/test_thresh.cpp .

And, Can I take reference from static void test_threshold( const Mat& _src, Mat& _dst, double thresh, double maxval, int thresh_type, int extra_type ).

And I think after this we can call the following similar functions as accuracy tests for adaptiveThreshold.

TEST(Imgproc_Threshold, accuracyOtsu) { CV_ThreshTest test(CV_THRESH_OTSU); test.safe_run(); }

@Dhanwanth1803, let's start with adding to test_thresh.cpp. Use cv::threshold as a reference. Please open PR once test passed locally for easier discussion.

@dkurt okay sir. Will do.
