2014-04-25 08:20:22 -0600 | asked a question | Can I real-time recognize face I want to know how to real-time recognize face.now, I have train a database, but when I detect face region, I don't know how to get the region. Does onCameraFrame() function support deal a frame. |
2014-04-25 07:52:27 -0600 | asked a question | I'm developing a project about face recognition on android. I meet a problem after detect face region I meet a problem in the onCameraFrame() function. After detect face in the function, I want to get the face region, and then create a new Mat to save the face area. but there are a problem.My code is: I want to get the face area, so I use the gray image to init the new Mat data. My error is while the program is right if I move the penultimate sentence
I want to know why is it. thanks |

2014-04-21 03:17:52 -0600 | commented question | I am developing face recognize on android,why the predict method always return 0 the closest is meaning first push_back()? I really don't set the threshold, but I using threshold init the createFisherFaceRecognizer() method. |
2014-04-21 02:32:15 -0600 | asked a question | I am developing face recognize on android,why the predict method always return 0 I was developing face recognize on android, but I missed a problem, when I use the predict method to predict persons, the return values is 0 everytime. The api sad that -1 states this face is unknown. Now,I want to know why is it. could you help me. thanks! My code |
