C++ Tool That Extracts Text From Scrolling Screen Recordings
Palimpsest: I Built a C++ Tool That Extracts Text From Scrolling Screen Recordings (94% Accuracy, 323 FPS on a Laptop) Most of the code was AI-generated from a detailed architecture prompt. I designed the pipeline, the AI wrote the C++. Here's what we built. I had a problem. My dad takes 1.5 hour long banking regulation classes recorded as screen recordings of someone scrolling through RBI…
C++ programmer creates tool to extract text from scrolling screen recordings, achieving 94.56% accuracy and 323 FPS on a laptop. Named Palimpsest, the software is designed to convert long banking regulation video lectures into clean text files. The tool uses a lock-free pipeline with bounded queues and dwell gating to filter out motion-blurred frames and focus on stable, stable content.
It also handles overlapping frames by fuzzy stitching and cross-GAP deduplication. The software runs efficiently on both CPU and GPU, making it ideal for offline, local transcription of scrolling document videos.
