Introduction to Computer Vision
Computer vision is a field of artificial intelligence that trains computers to interpret and understand the visual world. By digitally processing images and videos, machines can accurately identify and classify objects—and then react to what they "see."
How Computer Vision Works
At its core, computer vision involves acquiring, processing, analyzing, and understanding digital images to extract high-dimensional data from the real world. This process enables decision-making based on that data. Key technologies behind computer vision include machine learning and deep learning, which allow computers to learn from visual data in a way similar to humans.
Key Components of Computer Vision
- Image acquisition
