In some Video i tracked an moving object. I extract the width and height in pixels and set these values as limit for my plot diagram. Now i want to get the tracked points in the diagram.
What I'm currently doing:
while hasFrame(videoReader)
frame = readFrame(videoReader);
[points,validity] = tracker(frame);
out = insertMarker(frame,points(validity, :),'+');
writeVideo(v1, out);
videoPlayer(out);
end
close(v1);
release(videoPlayer);
plot(points(:,1),points(:,2));
xlim([0 imageWidth])
ylim([0 imageHeight])
imageWidth and imageHeight are getting extracted from the first frame. The plotting is actually showing something, but the graph is not corresponding to my real tracked points. The Image is a 2D image, like looking from top on a table. So i only need x and y coordinates in pixels of the points and plot them.
What am I doing wrong?
