I am trying to track 3 points of a moving video.First i insert those points and while video playing i want track those points path using x & y values.
num_frame=1; ex_points = {};
while ~isDone(videoFileReader)
frame = videoFileReader();
[points,validity] = tracker(frame);
ex_points{num_frame} = points;
out = insertMarker(frame,points(validity, :),'+','size',10);
% Where position is for one or more disconnected lines, an M-by-4 matrix, where each four-element vector [x1, y1, x2,y2], describe a line with endpoints, [x1 y1] and [x2 y2].
videoPlayer(out);
num_frame = num_frame+1;
end
I able to store the values in to array,
ex_points{num_frame} = points;
then i try to print one record using below code,
disp(hist_points{5});
the result was like below,

disp(hist_points{5}(1)); % for first element in cell 5
Read up in the documentation on cell arrays about dereferencing.
