# Dense Slides: Architecting and Testing Controllable Agents: Lance Martin

## Source Video
[Architecting and Testing Controllable Agents: Lance Martin](https://www.youtube.com/watch?v=ib-wTAvCZqg)

## 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

- Recreated text/layout view: [open HTML recreation](/assets/slide-recreations/dense/ib-wTAvCZqg/slide-001.html)
- AI slide classifier: `content_slide` confidence `0.98`
- Text source: advanced OCR `rapidocr-live/bright-screen/opencv-adaptive`.
- OCR decision: ready — Small diagram labels and code-like text are better handled by OCR than direct transcription.

- Recreated text/layout view: [open HTML recreation](/assets/slide-recreations/dense/ib-wTAvCZqg/slide-003.html)
- AI slide classifier: `content_slide` confidence `0.97`
- Text source: none.
- OCR decision: ready — Dense code screenshot with small text; OCR will outperform manual reading.
- Slide text: not surfaced (`illegible` by AI classifier).

- Recreated text/layout view: [open HTML recreation](/assets/slide-recreations/dense/ib-wTAvCZqg/slide-004.html)
- AI slide classifier: `content_slide` confidence `0.98`
- Text source: advanced OCR `rapidocr-live/bright-screen/opencv-adaptive`.
- OCR decision: ready — Dense chart labels and small comparison text; OCR is the cheaper pass.
