Why this question was delete? I want to take suggestions which approach should be used?

Hi,

I am newbie to Open CV. I am in a situation where I have to decide whether I have to buy IRIS device for eye detection and recognition or I should do RnD to build application using Open CV which provides Eye recognition feature for Attendance system? Please recommend which is the better approach in terms of performance and money? Currently I have option to buy device from http://www.iritech.com/. Please recommend accordingly which is the best approach from the above mentioned or any other? I have android phones and need suggestions for that.

Best Regards,

Hi,

I am trying to detect real time face detection. I have run face-detection-sample but the problem is sample is also detecting the faces from images as well. How can I setup Open CV to detect real time faces and ignoring images??

Thanks in advance.

Hi I am trying to detect the tilted face using Opencv4android. I have run face-detection-sample, I have noticed that when face is straight, its detected but when the face is right/left tilted or upward then it is not detected. What is the reason behind it?

How tilted face detection is implemented?

Hi, I have integrated opencv4android face detection sample. I want to show Camera in Portrait mode, the thing is the default JavaCameraView is rotated 90 degree to the left. I apply some rotation on CameraBridgeView and JavaCameraView but after that I am unable to detect the faces.

CameraBridgeViewBase.java

deliveAndDrawFrame() {
                Matrix matrix = new Matrix();
                matrix.preTranslate((canvas.getWidth() - mCacheBitmap.getWidth()) / 2,(canvas.getHeight() - mCacheBitmap.getHeight()) / 2);
                if(cameraId == Camera.CameraInfo.CAMERA_FACING_FRONT) {
                    matrix.postRotate(-degrees,(canvas.getWidth()) / 2,(canvas.getHeight()) / 2);
                } else {
                    matrix.postRotate(degrees,(canvas.getWidth()) / 2,(canvas.getHeight()) / 2);
                }
                canvas.drawBitmap(mCacheBitmap, matrix, new Paint());
}

The above function has shown the preview right to my requiremnt in Portrait mode. I also adjusted the Camera orientation as JavaCameraView

initializeCamera() {
....
int degrees = getCameraDisplayOrientation();
mCamera.setDisplayOrientation(degrees);
......
}

Can anyone please let me know what can be the issue? Why after this I am unable to detect the faces?

Hi,

I have integrated OpenCv For Android successfully but the problem is it also shows false negatives. Sometimes it show faces when there is not. I have tried to set the setMinFaceSize to .5, .4,.3.2 all shows fase negativs, How to eradicate false negatives?
