## What it is
SmartCamera is an Android camera extension library providing a highly customizable real-time scanning module that detects whether an object's border inside the camera matches a specified region. It combines a camera view with a mask overlay and an OpenCV-based native scanner for use cases like ID cards, business cards, and document scanning with auto-capture and cropping.

## Use cases
- scan id cards with android camera
- detect document borders in real time
- auto-capture when card fits the frame
- build a business card scanner app
- real-time edge detection on camera preview frames
- tune scanning algorithm parameters for better recognition

## When to choose
- you need real-time border detection on Android camera preview streams
- you are building a document or card scanning feature with auto-capture
- you want tunable OpenCV-based scanning parameters with a debug preview mode

## When to avoid
- you need to crop a single static photo rather than a live camera stream (use SmartCropper instead)
- you target platforms other than Android
- you need an actively maintained library with recent releases or a clear license
