function S=int2struct(R,G,B)
%INT2STRUCT Convert intensity movie frames to a movie structure.
%   INT2STRUCT(I) converts a 3-D intensity movie array, I, into a
%   standard MATLAB movie structure.
%
%   INT2STRUCT(R,G,B) converts separate 3-D intensity movies R, G,
%   and B, representing the red, green, and blue color planes of an
%   RGB video, respectively, into a standard MATLAB movie structure.
