You can use DroidCam if you are using an android phone. You'll need to install OS Generic Video Interface driver.

Hope it helps. :)

With the iPhone, using the App suggested by Ashish above (IP Cam), you can achieve the same pretty easily! The code is exactly the same:
url = 'http://<ipaddress>:8020/image.jpg';
ss = imread(url);
fh = image(ss);
while(1)
ss = imread(url);
set(fh,'CData',ss);
drawnow;
end

Here's the working code for color detection using android camera:
url = 'http://192.168.0.100:8080/shot.jpg';
framesAcquired = 0;
while (framesAcquired <= 50) % the vedio will work till the 50 video frames, after that the vedio will stop. You can use while(1) for infinite loop
data = imread(url);
framesAcquired = framesAcquired + 1;
diff_im = imsubtract(data(:,:,1), rgb2gray(data)); % subtracting red component from the gray image
diff_im = medfilt2(diff_im, [3 3]); % used in image processing to reduce noise and for filtering
diff_im = im2bw(diff_im,0.18); % convert image to binary image
stats = regionprops(diff_im, 'BoundingBox', 'Centroid'); % measures a set of properties for each connected component in the binary image
drawnow;
imshow(data);
hold on
for object = 1:length(stats)
bb = stats(object).BoundingBox;
bc = stats(object).Centroid;
rectangle('Position',bb,'EdgeColor','b','LineWidth',2)
plot(bc(1),bc(2), '-m+')
end
hold off
end
%stop(vid); % to stop the video
%flushdata(vid); % erase the data video
clear all

I am not sure if this is exactly what you are looking for. However, you can use 'Simulink Support Package for Samsung GALAXY Android Devices' or 'Simulink Support Package for Apple iOS Devices' to access the appropriate smartphone camera. Both these support packages come with a Camera block that allow you to get the Camera data inside MATLAB. You can subsequently connect the Camera block to a Video Viewer block if you would like to visualize the data in Simulink.

You would either have to write the code in MATLAB and use MATLAB Coder, or else you would have to create a Simulink model and deploy that to Android.

You need to replace he "MY_IP " part by your actual IP address, such as http://192.168.0.10/shot.jpg

Hi All,
I found out that;
imread('http://MY_IP /shot.jpg');
works only on secured network for me. If I am on a public network, then it gives error.
