Hi All,
I am currently working with the Kinect V2 to develop a method of tracking respiratory motion.
How can I model and plot the depth changes over time? From looking into the array the depth image stores, the depth seems to be an index between the height and width.
For simplicity I want to plot the depth changes of a 5x5 pixel square in the center of the screen over 300 frames, so roughly 10 seconds. (I'll change the frequency to fixed 10 Hz later) but right now i'm stuck on the basics.
Any help would be appreciated!
Thank you in advance.

maxFrame = 300;
vid = videoinput('kinect', 2); %1 for color, 2 for depth
vid.FramesPerTrigger = 1;
vid.TriggerRepeat = maxFrame;
start(vid);
for nFrame = 1 : maxFrame
d = getdata(vid);
[h,w,p] = size(d);
hh = floor(h/2);
hw = floor(w/2);
d55 = d(hh-2:hh+2, hw-2:hw+2,:);
...
end

Sorry, reading that back makes it sound silly. I appreicate and have accepted your answer!

No it isn't silly: it is just that typically the arrays are even length and then it becomes a challenge to say what the center pixel is.
