Hi Deepz,

If you wish to analysis image file, VDM is enough.

There's a function called IMAQ ReadFile under Vision and Motion>>Vision Utilities>>File for image file loading purpose.

If you wish to acquire live image, you need Vision Acquisition Software, https://www.ni.com/en-us/shop/product/vision-acquisition-software.html, together with a frame grabber, https://www.ni.com/en-us/shop/category/machine-vision.html, and camera in order to acquire an image for processing on PC.

Regards, Kate

Hi deepz,

I've attached a screen shot of a very simple block diagram that uploads an image from file and displays it on the front panel. If you wish to use images from your webcam, you have two options:

1. Acquire and save an image from your webcam using a separate software and then upload the image using the example I've included.
2. Download NI-IMAQ for USB and use those vi's to acquire data from your webcam and incorporate that into your program. That driver includes three examples that shows how to acquire data from a USB camera.
