I want to accelerate the webcam frame rate withdraw of the code below, I wasn't able to do that using 'parfor' from parallel computing toolbox, since the new created workers don't have 'cam' object (I think).

Any suggestions how to maximize the frames withdraw ?

Thanks!

clear all; clc;
len = 100;
weblist = webcamlist;
cam = webcam(string(weblist(1,1)));
img = snapshot(cam);
[r, c, ~] = size(img);
vid = zeros(r, c, 3, len);
tic
for i=1:len
    vid(:, :, :, i) = snapshot(cam);
end
toc
clear('cam');
