You Can Scan a Book Quickly with High-Res Video and No Special Hardware (orner.com)

A new method allows users to scan physical books quickly using just a smartphone camera and high-resolution video, eliminating the need for specialized hardware. By capturing video of a user turning the pages, followed by post-processing with Optical Character Recognition (OCR) and AI, the system generates a Markdown text file containing the book's content along with processed images. The technique enables the digitization of an entire 400-page book in about 30 minutes, leveraging advanced processing to compensate for common scanning issues such as page curl and skew. This approach is significant for the AI/ML community as it democratizes book digitization, making it accessible to anyone with a smartphone. The process employs a small Python command-line tool that utilizes advanced algorithms for frame analysis, local OCR, and merging multiple readings of the same page. Notably, resolution is critical; scanning in 4K enhances OCR accuracy significantly. The method's reliance on AI for merging and problem-solving further showcases the potential of combining traditional techniques like video capture with cutting-edge AI, offering an innovative solution for archiving and preserving written content.
