yescan - PDF OCR Scanner
Overview
The mobile document digitization tool yescan - PDF OCR Scanner, published by Nth Power, is designed to replace traditional hardware scanners by transforming mobile cameras into digital capture and document processing systems. The application targets mobile productivity by addressing the challenges of physical-to-digital workflows: perspective distortion, varying lighting conditions, background clutter, handwritten interference, and static PDF barriers to content reusability. By combining automated computer vision algorithms with Optical Character Recognition (OCR), YeScan allows users to capture, clean, manipulate, and export physical documents across formats including PDF, Word DOCX, Excel XLSX, and plain text.
From an image processing perspective, YeScan utilizes border detection and perspective rectification algorithms to identify document boundaries against contrasting surfaces, correct angled captures, and flatten keystoned pages. Its post-processing pipeline includes an Ultra-HD enhancement engine that eliminates uneven shadows, sharpens degraded typography, and removes moiré interference patterns when photographing digital displays, PPT presentations, or projection screens. The application also features automated inpainting and handwriting removal tools, allowing users to strip annotations, marginalia, and pencil marks from forms and contracts to restore clean base documents.
For document manipulation, com.yescan.intl provides tools that go beyond basic image capture. Its OCR engine performs character recognition while preserving the geometric layout, tabular structures, and paragraph hierarchies of original physical documents. This structural preservation enables the direct export of paper balance sheets, invoices, and ledgers into fully editable Microsoft Excel spreadsheets, as well as contracts into Microsoft Word documents. The built-in PDF management suite allows users to merge pages, delete sheets, apply personalized watermarks, and insert cryptographically saved digital signatures directly on the mobile device, streamlining document workflows.

FAQs
How does YeScan remove handwriting and annotations from scanned documents?
YeScan utilizes image segmentation and inpainting algorithms that detect differences in ink coloration, stroke pressure, and layer characteristics to erase manual writing while preserving the underlying printed text and document background.
Can scanned receipts and tabular sheets be converted into editable Excel files?
Yes, the OCR engine analyzes structural table borders and data column alignments to parse numeric entries and labels directly into editable .xlsx format.
Is an active data connection required for basic document scanning and cropping?
Basic image capture, edge detection, perspective correction, and local PDF compilation function locally on the device hardware without requiring an active internet connection.
What file formats does YeScan support for export and saving?
The application exports processed scans into searchable PDF, Microsoft Word (DOCX), Microsoft Excel (XLSX), JPEG image sequences, and plain text (TXT) formats.
How does the screen recording and PPT shooting feature mitigate display moiré?
The app applies spatial frequency filtering to suppress the high-frequency grid interference patterns that typically appear when photographing LCD screens and computer monitors.
