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.

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.

445349dd7d Same fix as with the houghcircles

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.

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.

1740218ee0 small platform compatability fix for ESC key 2016-03-29 20:02:35 +03:00
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.
