    Computer vision is a field of artificial intelligence (AI) that enables computers and 
    systems to derive meaningful information from digital images, videos and other visual 
    inputs — and take actions or make recommendations based on that information. 
    If AI enables computers to think, computer vision enables them to see, observe and understand.
    **👈 Select a demo from the sidebar** to see some examples of what Computer Vision can do!
