#Bitmap Smart Clipping using OpenCV
based on http://code.taobao.org/p/tclip/
recommend iOS version: https://github.com/croath/UIImageView-BetterFace
#Demo Screenshots
#Features
- using OpenCV to detect faces firstly, if have faces, won't cut faces off
- using OpenCV to detect other characters secondly, if found significant zone, won't cut it off
- using FAST feature detector instead of SURF, thanks for @yanunon
#Usage
copy config file to app dir
String configPath = TClip.copyConfig(context, TClip.CONFIG, R.raw.haarcascade_frontalface_alt);get cropped bitmap
//config: /data/data/com.demo.tclip.debug/haarcascade_frontalface_alt.xml Bitmap ret = TClip.crop(configPath, sourceBitmap, width, height);
#Build
- download OpenCV & unzip to /home/user/opencv-android-sdk
- export OPENCV_PACKAGE_DIR="/home/user/opencv-android-sdk"
libnonfree.so & libopencv_java.so from beartung/nonfree-opencv-android- using FAST feature detector without libnonfree
- cd jni && ndk-build
