问题
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.
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?
回答1:
I'd suggest getting the Android OpenCV port working as a good first step.
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.
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.

what about face.com? it's web(service) based, but supposed to be pretty good!
