hey guys i want to know if it is possible to convert in real time a RGB form video to a gray Form.
I tried to use rgbgray function and min function but i wasn't able to get what i want
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
%activate the integrated camera
web = webcam('HD Webcam')
img = snapshot(web)
% Read in a demo image.
%grayImage= min(originalRGBImage, , 3); % Useful for finding image and color map regions of image.
grayImage = rgbgray(web); % Useful for finding image and color map regions of image.

You need to pass in the color image, not the webcam object. And you need to call rgb2gray(), not rgbgray().
rgbimage = snapshot(web)
grayImage = rgb2gray(rgbImage);
