Computer vision (en-US)
Computer vision is a field of artificial intelligence that helps computers interpret and understand visual information from the real world—such as images, video, and sometimes depth data from sensors. The goal is to “see” and extract meaningful information, like identifying objects, recognizing faces, detecting motion, reading text, estimating depth, or understanding scenes. Common tasks include image classification (labeling what’s in an image), object detection (finding and locating items), semantic segmentation (labeling each pixel by category), and optical character recognition (OCR) for reading text. In video, systems may track objects over time, recognize actions, or detect events. Typical methods use machine learning, especially deep neural networks, trained on large datasets. Models learn patterns in pixels and features, then generalize to new images. Accuracy depends on factors like data quality, lighting and camera conditions, and how well the training data matches the real-world environment. Applications range from medical imaging support and quality inspection in manufacturing to autonomous driving assistance, robotics, and image search. Because visual systems can fail in unexpected ways (for example, under unusual lighting or with rare objects), careful evaluation and monitoring are important.

FAQ
1) What’s the difference between computer vision and image processing? Computer vision focuses on understanding and interpreting visual content (often with AI), while image processing is broader and may include enhancement, filtering, and transformations. 2) Do computer vision systems “understand” like humans? They learn statistical patterns from data and can perform tasks reliably in specific contexts, but they don’t have human-level understanding or common sense. 3) What data do computer vision models need? Usually labeled images or videos (e.g., bounding boxes, masks, or class labels), plus validation data to measure performance.
