Google Deepmind ## Source Video [Real-time Experiments with an AI Co-Scientist - Stefania Druga, fmr. Google Deepmind](https://www.youtube.com/watch?v=wNH3q9pqn0U) ## Method This deck is slide-only. The existing captured video frame set supplies candidate frames, then local OpenCV rejects sponsor/title/speaker-only frames, crops visible slide surfaces, deduplicates, and saves the cropped slide images. ## Cropped Visible Slides ![[assets/dense-slides/wNH3q9pqn0U/slide-001.jpg]] - Recreated text/layout view: [open HTML recreation](/assets/slide-recreations/dense/wNH3q9pqn0U/slide-001.html) - AI slide classifier: `content_slide` confidence `0.98` - Text source: agent_vision. - OCR decision: ready — Dense product UI screenshot with multiple small labels and panels.
