function T = perform_voting_ball(M,sigma,c,p,n)

% perform_voting - perform the voting process for the ball field.
%
%   T = perform_voting_ball(M,sigma,p,n);
%
%   'M' is a 2D function made by the user (1 for features and 0 in the background).
%   
%   Optional:
%   'sigma' and 'c' control the stick field (see 'compute_stick_tf').
%   'n' is the size of the kernel (typically smaller than the size of the image).
%   'p' is the precision for the computation of the ball tensor field.
%
%   See also perform_voting.
