What is the technology behind Google Lens?

Google Lens is powered by a combination of computer vision, optical character recognition (OCR), and machine learning technologies. At its core, it uses convolutional neural networks (CNNs) to analyze images and detect objects, text, and patterns. For text recognition, Google Lens integrates OCR capabilities similar to Google’s Tesseract, enhanced with deep learning for higher accuracy across diverse fonts and languages. Additionally, the app uses Google's vast knowledge graph and cloud-based AI services to provide contextual information, such as identifying landmarks or extracting details from scanned documents. These technologies enable Google Lens to perform tasks like real-time translation, product identification, and augmented reality applications.
