%BLUR  Smoothes an image using the normalized box filter
%
%    dst = cv.blur(src)
%    dst = cv.blur(src, 'KSize', [5,5], ...)
%
% ## Input
% * __src__ Source image.
%
% ## Output

%
% ## Options
% * __KSize__ Smoothing kernel size. default [5,5]
% * __Anchor__ Anchor point. The default value Point(-1,-1) means that

% 
%    K = ones(KSize) / prod(KSize)
