Perspective document deskewer, shadow remover, and multi-page A4 PDF binder
Document Scan Deskewer is a local Linux desktop utility for straightening skewed receipts, whiteboards, book pages, and paper documents, removing uneven shadows, sharpening text, and binding multi-page scans into clean A4 or US Letter PDFs. An independent Linux desktop alternative to CamScanner for perspective document rectification, shadow removal, and offline PDF assembly without cloud uploads.
Key Features:
- 4-Corner Perspective Rectifier: Interactive 4-handle quad selector with exact 8-DOF homography matrix solver (pure-Python Gaussian elimination), bicubic full-resolution warping, automatic border detection, and fine deskew angle adjustment with projection-variance auto-alignment.
- Shadow Removal & Crisp Document Filter: Local illumination flattening via blurred background division, Clean Black & White adaptive contrast mode, Grayscale Paper mode, and Magic Color text sharpening.
- Multi-Page Queue & A4 PDF Binder: Batch process multiple scanned pages, reorder pages, export individual PNG/JPEG images, or compile a combined multi-page A4/Letter PDF locally via QPdfWriter.
Disclaimer: Document Scan Deskewer is an independent open-source project by TC Studio and is not affiliated with, endorsed by, or sponsored by INTSIG Information Co..
