smartcrop implementation in Java
smartcrop finds good crops for arbitrary images and crop sizes, based on Jonas Wagner's smartcrop.js
test code will analyze 12 images, analyze took 30ms 640x470.

## Example
> [check test code](https://github.com/QuadFlask/smartcrop-java/blob/master/src/test/java/com/github/quadflask/smartcrop/SmartCropTest.java)
```java
BufferedImage img = ImageIO.read(new File("source.jpg"));
CropResult result = new SmartCrop().analyze(img);
ImageIO.write(result.getBufferedImage(), "png", new File("debug.png"));
- crop feature
- analyze after scale down for performance
- face detection
- remove alpha channel for jpg format
