i've got the code below:
vid=videoinput('winvideo',1,'YUY2_1024x768');
preview(vid);
for k = 1:10
frame = getsnapshot(vid);
end
frame1 = rgb2gray(frame);
figure,image(frame1);
level = graythresh(frame1);
frame3 = im2bw(frame1,level);
figure,image(frame3);
delete(vid);
closepreview(vid);
the problem here is that i don't know what type of image i can get from my camera on my laptop (RGB,HSV, or something else)! the result is not as i expect ! here is the result:
hope someone can help me !

dev_info = imaqhwinfo('winvideo', 1);
char(dev_info.SupportedFormats)
will show you the supported formats

The cameras I deal with all have an RGB mode. Why don't you just cut your losses and switch to a camera that uses an RGB mode? Otherwise you'll have to use ycbcr2rgb() to convert your yuy2 image into rgb. This page may be helpful: http://www.fourcc.org/yuv.php
