I have been using LabVIEW for almost 4 years now. I can implement various Image processing techniques in LabVIEW like Background Subtraction, Background Subtraction using LabVIEW FPGA, Color and Pattern Matching algorithms, Object tracking using different techniques, Image segmentation, Cropping, Scaling, Color and Contrast change, edge detection, canny edge detection and all the other tools available. I can also do all this in openCV and then create a LabVIEW program to call that openCV dll.
