我的第一个Android应用程序将要涉及的前置摄像头和面部EX pression认可。我做了很多研究，但我无法找到任何涉及面前pression识别任何Android的库。我基本上要测量的反应。

My first Android app is going to involve a front facing camera, and facial expression recognition. I did a lot of research, yet I couldn't find any Android libraries that involve any facial expression recognition. I basically want to measure reactions.

我想那一定是在某些应用程序的某个地方做的，任何人都可以点我的研究方向是正确的？如果没有在Android中，也许有人会知道一个图书馆，我可以通过端口？

I'm thinking it MUST have been done somewhere in some app, can anyone point my research in the right direction? If not in Android, perhaps somebody may know of a library that I can port over?

推荐答案

我会建议获得的 Android的OpenCV的端口的工作作为一个良好的开端。

I'd suggest getting the Android OpenCV port working as a good first step.

由于对图像处理的实时性要求，大部分的人脸检测/识别code，你会看到很可能是在C ++中。许多系统可以使用的OpenCV为基础和/或可以凑齐来自OpenCV中的许多低级别的功能，合理的解决方案。

Due to real-time requirements for image processing, most of the face detection/recognition code you're going to see is likely to be in C++. Many systems may use OpenCV as a base and/or you can cobble together a reasonable solution from OpenCV's many low-level functions.

在那里CVCamera样品也是很好的显示了如何JNI / NDK互操作性的工作在Android上它可以有助于与其他code接口。

The CVCamera sample in there is also good for showing how JNI/NDK interop works on Android which can be helpful for interfacing with other code.
