Document Scanner Kit

Capture, deskew, export — entirely on device.

On-device document capture with two interchangeable detection engines — ML Kit for size, OpenCV for accuracy — plus manual corner adjustment and perspective correction.

Detecting edges

What Is Inside

Two Detection Engines

ML Kit adds about 0.27 MB; OpenCV adds roughly 25 MB per ABI and detects better. The kit documents both figures with their baseline so the choice is informed.

Explicit Decisions

Which contour is the document and which corner is top-left are the kit's decisions, not the library's — written in pure Kotlin and covered by tests.

Manual Corner Adjustment

Users can correct the detected quadrilateral, with movement rules that reject degenerate shapes before they reach the export.

Perspective Correction

Deskew and crop to a clean rectangle, with size recipes for the common paper formats.

Four Languages

English, German, French and Turkish, with a canonical-text mechanism that flags every translation whose English source has changed.

Checked Machinery

273 tests and a verification layer whose own checks are probed against broken fixtures — because the checks are where defects concentrate.

Product Description

📄 Document Scanner Kit

On-device document capture for Android: detect the page, let the user correct the corners, deskew it, and export a clean result. Nothing leaves the device.

This kit is still in development. The engine layer, corner adjustment and the four language sets are in place; instrumentation on physical hardware and the store materials are not finished yet.

  • Two interchangeable detection engines: ML Kit and OpenCV
  • Documented APK cost for each engine, per ABI
  • Manual corner adjustment with degenerate-shape rejection
  • Perspective correction and common paper size recipes
  • English, German, French and Turkish
  • 273 tests and a probed verification layer

📄 Document Scanner Kit

Android için cihaz üzerinde belge yakalama: sayfayı algıla, kullanıcının köşeleri düzeltmesine izin ver, perspektifi düzelt ve temiz bir sonuç üret. Hiçbir şey cihazdan çıkmıyor.

Bu kit henüz geliştirme aşamasında. Motor katmanı, köşe düzeltme ve dört dil hazır; fiziksel donanımda enstrümantasyon ve mağaza materyalleri henüz tamamlanmadı.

  • Değiştirilebilir iki algılama motoru: ML Kit ve OpenCV
  • Her motor için ABI başına belgelenmiş APK maliyeti
  • Bozuk şekilleri reddeden manuel köşe düzeltme
  • Perspektif düzeltme ve yaygın kağıt boyutu tarifleri
  • İngilizce, Almanca, Fransızca ve Türkçe
  • 273 test ve problanmış bir doğrulama katmanı

📄 Document Scanner Kit

Dokumentenerfassung auf dem Gerät für Android: Seite erkennen, Ecken vom Nutzer korrigieren lassen, entzerren und ein sauberes Ergebnis exportieren. Nichts verlässt das Gerät.

Dieses Kit befindet sich noch in Entwicklung. Die Engine-Schicht, die Eckenkorrektur und die vier Sprachsätze stehen; Tests auf echter Hardware und die Store-Materialien fehlen noch.

  • Zwei austauschbare Erkennungs-Engines: ML Kit und OpenCV
  • Dokumentierte APK-Kosten je Engine, pro ABI
  • Manuelle Eckenkorrektur mit Ablehnung entarteter Formen
  • Perspektivkorrektur und gängige Papierformat-Rezepte
  • Englisch, Deutsch, Französisch und Türkisch
  • 273 Tests und eine geprüfte Verifikationsschicht

📄 Document Scanner Kit

Capture de documents sur l’appareil pour Android : détecter la page, laisser l’utilisateur corriger les coins, redresser et exporter un résultat net. Rien ne quitte l’appareil.

Ce kit est encore en développement. La couche moteur, l’ajustement des coins et les quatre langues sont en place ; les tests sur matériel physique et les visuels boutique ne sont pas terminés.

  • Deux moteurs de détection interchangeables : ML Kit et OpenCV
  • Coût APK documenté pour chaque moteur, par ABI
  • Ajustement manuel des coins avec rejet des formes dégénérées
  • Correction de perspective et formats de papier courants
  • Anglais, allemand, français et turc
  • 273 tests et une couche de vérification sondée

Your Data Stays Yours

The kit performs all detection and correction on the device. It makes no network calls, collects no analytics and sends no images anywhere.
