Question

咋样在android里实现将人的头像从图片里扣出来（不要头发）如下图，抠图只剩下两个人头（不带头发）求解，各位大虾帮帮小弟

Answer 1

你是想做图像处理的吗？如果是的话，推荐使用opencv ,这个有个开源的android opencv库，可以使用opencv来进行抠图~~

Answer 4

svn获取opencv的源代码：svn checkout http://android-opencv.googlecode.com/svn/trunk/ android-opencv 建议放在home下
3 下载android-ndk-r4-crystax 记住，一定要是crystax，来自google官方的解释就是标准ndk是不支持opencv的编译的，建议放在home
*************************记住,openv的源码和ndk的源码一定要是在同级目录下不知道是不是说的这个问题，我没有编过opencv，你自己谷歌看看吧~~~
