An Android library for smart image cropping that automatically detects document borders using OpenCV (with an optional TensorFlow Lite HED model for improved detection), lets users adjust the selection with draggable anchors and a magnifier, and crops with perspective transformation to rectify the region. It is aimed at photos of ID cards, business cards, and documents.

Use cases

• crop and straighten photos of documents on android
• automatically detect document borders in a photo
• scan id cards or business cards with a phone camera
• perspective-correct a skewed document photo
• let users manually adjust crop selection with magnifier
• build a document scanner app on android

When to choose

• you need an Android view component for smart document cropping with edge detection
• you want automatic border detection plus manual anchor adjustment in one library
• you need perspective correction to produce a front-facing crop of a document

When to avoid

• you need cropping on iOS, web, or desktop platforms
• you need full OCR or text extraction from documents
• your project requires a permissive license - the repo has no explicit license file
• you need real-time camera border detection rather than cropping still images (see SmartCamera instead)
