Hi
Please tell me how to organize a circular buffer of images from the camera.
This is my code that allows to shoot a image stream. And I want to write them to a circular buffer for later processing
clear all;
devs = webcamlist;
cam = webcam(devs{1});
global LOOP_RUNNING;
LOOP_RUNNING = true;
img_display = figure('CloseRequestFcn',@my_closereq);
while (LOOP_RUNNING)
img = snapshot(cam);
subplot(2,2,1),imshow(img);
pause(0.05);
end
function my_closereq(~,~)
global LOOP_RUNNING;
LOOP_RUNNING = false;
delete(gcf);
clear('cam');
return;
end

You can refer to the Insert elements into a 4D array MATLAB Answer which might help you to get started on your implementation. The following resource might also help: circular buffer.
