Muhammad Abdullah	c180047bc1	update digits_video.py Following were the errors in the digits_video.py 1 ) The code was not working because data type of x was float however in "cv2.rectangle" we require integer . 2 ) After pressing the "esc" button the image windows did not destroy So I amended following things: 1 ) ~converted data type of x to int.~ Used Python integer division (//) 2 ) used cv2.destroyAllWindows() to close all windows after the press of "esc" by user.	7 years ago

Mark Szumowski	94d63d4281	Update research paper link in Python sample The docstring for one of the Python sample programs includes a link to the research paper describing the main algorithm. That link is no longer valid (results in a 404 error) so this update replaces it with another link from the same institution which is currently valid.	8 years ago

Cartucho	fcddfa4f86	GSoC 2016 - Adding ALIASES for tutorial (#7041 ) * GSoC 2016 - Adding toggle files to be used by tutorials. Add a toggle option for tutorials. * adds a button on the HTML tutorial pages to switch between blocks * the default option is for languages: one can write a block for C++ and another one for Python without re-writing the tutorial Add aliases to the doxyfile. * adding alises to make a link to previous and next tutorial. * adding alias to specify the toggle options in the tutorials index. * adding alias to add a youtube video directly from link. Add a sample tutorial (mat_mask_opertaions) using the developed aliases: * youtube alias * previous and next tutorial alias * buttons * languages info for tutorial table of content * code referances with snippets (and associated sample code files) * Removing the automatic ordering. Adding specific toggles for cpp, java and python. Move all the code to the footer / header and Doxyfile. Updating documentation.	8 years ago

Aleksandar Atanasov	445349dd7d	Same fix as with the houghcircles Moved second `imshow()` inside the if-statement to prevent error when no lines have been found and the function is called with an empty `cdst`.	9 years ago
Aleksandar Atanasov	c5bbc0353c	Added small fix when circles are not detected I noticed that I missed the fact that `cimg` is used in the second `imshow()` call. Changed the scope of the second function call to be within the if-statement. Otherwise in cases where have not been detected the second `imshow()` will attempt to use `cimg` which will be empty leading to an error.	9 years ago
Aleksandar Atanasov	25e2e8aa3c	Removed trailing spaces at line 32	9 years ago
Aleksandar Atanasov	14deab252b	Fix houghlines.py when no lines found In the C++ equivalent of this example a check is made whether the vector (here in Python we have a list) actually has any lines in it that is whether the Hough lines function has managed to find any in the given image. This check is missing for the Python example and if no lines are found the application breaks.	9 years ago

Anatoly Orlov	1740218ee0	small platform compatability fix for ESC key	9 years ago
Anatoly Orlov	2be805ce29	kalman.py was broken totally 1. Following condition is True on each iteration becuase -1 % 0xFF is 255 not -1 code = cv2.waitKey(100) % 0x100 if code != -1: break this were resetting point position on each cycle not on key press as intended 2. Previous small bug were masking serious bug with matrix operation on matrices of incorrect size. As the result on 2nd iteration of internal cycle program has crushed. I have fixed it too, matrix operation was taken from examples/cpp/kalman.cpp where it looks like randn( processNoise, Scalar(0), Scalar::all(sqrt(KF.processNoiseCov.at<float>(0, 0)))); which is something totally different from previous code here. Example behave as it should now, i.e. point moving by circle trajectory as in C++ example.	9 years ago
