OpenCv 可实现的特效

灰度化方法二值化滤镜
边沿轮廓检测素描滤镜
怀旧色滤镜连环画
冰冻滤镜熔铸滤镜
浮雕滤镜

OpenCv  for Android 步骤

去OpenCv 下载android 版SDK   导入Module  

直接静态初始化 

static {if(!OpenCVLoader.initDebug()) {Log.d("My App", "Unable to load OpenCV");} else {Log.d("My App", "OpenCV loaded");}
}

执行以上步骤后即可使用对应的api   

************************   该操作比较耗时,注意开启子线程进行对象获取   *********************************

详细代码如下:   具体运行效果自行复制粘贴
