Computer Vision

Computer vision is a field of artificial intelligence that enables machines to interpret and extract meaningful information from images and video. It encompasses tasks like image classification, object detection, facial recognition, optical character recognition, and scene understanding, all powered by deep learning models trained on large labeled image datasets.

In web development, computer vision surfaces in practical features more often than developers might expect. Image moderation services automatically flag inappropriate uploads. OCR extracts text from scanned documents for indexing. Product visual search lets users find items by uploading photos instead of typing keywords. Accessibility tools generate alt text descriptions for images. Cloud APIs from providers like Google Vision, AWS Rekognition, and Azure Computer Vision make these capabilities accessible without training custom models. For applications requiring specialized recognition, frameworks like TensorFlow.js can run lightweight vision models directly in the browser, enabling real-time processing without server round trips.
