Good day everyone, my name is Afrena. I am doing my final year project about detecting 2D defect using image processing. I have created my coding. It all work just fine. But i would like to have a preview of my webcam video of the binary coding that i have made, instead of just showing the captured image as my output. Below are my coding:

I'm also quite new with MATLAB and its function. If I made a mistake please let me know. Thank you for your help

sir，may be can not use preview to get the processed image

so，use your method，and display image in one figure，use while to loop，such as

while 1

im=snapshot(cam);

process……

figure(1); imshow()

pause(1)

end
