For Bug opencv#3714, user use the imshow() function without calling namedWindow() properly, because user did not know the implicit rule for imshow(). (i.e. without calling namedWindow implied calling namedWindow( ,CV__WINDOW_AUTOSIZE). Improve the Display Image Tutorial to educate the user for such implied rule. Put a note on documentation for Bug#3714 Revise the documentation regarding to imshow() function to better educate the user the implicit rule. (i.e. without creating the window before the imshow() function is the same as creating AUTOSIZE window)

There is release non-retained variable in UIImageToMat.
The problem has fixed in 2.4(not 2.4.10). I found same ticket for 2.4.
Thank you.
