It tracks eyes for some extent but if we close our eyes, sometimes mismatch occurs. You can check the video of that implementation here

Based on that I implemented till eye detection. But it does not help in Blink detection, Does it?

Yes I am able to detect eyes at the moment.

I have been working on the android application which requires a method to detect eye blink. So can any body suggest the method for eye blink detection that is easy to implement. I tried Hough circle method but it is not giving any result. So can any body please help me?

There is a library called numpy in opencv package. I just wanted to know what is its use? Do we have any equivalent library in opencv java package? I don't know anything about python, just asked out of curiosity.

I have created an application in Android using CamerBridgeViewBase to access camera. The application detects face and eyes in the captured frames. For some reasons I added a method to calculate Fps. Now my problem is, whenever a face is detected in the captured frame. The Fps will be almost same as given by enableFpsMeter(). If I focus my camera on some other areas such as plain wall the FpS will be more than the actual FpS. Why this is happening? How to solve this? I calculated FpS in the same way the opencv used in FpsMeter object to claculate FpS.

I had seen that code before. Still your comment was helpful!!! Thanks

Thanks for providing an example.

I know that but I want fps to be stored in a variable and should be able to use in some of the calculations I want to do on the image data obtained.

I am using CameraBridgeViewBase object to create an app that uses camera. I want frames per second to decide somethings in my app. How can I frames per second? can I use Videoio.CAP_PROP_FPS for this purpose?

When I used cascade classifier it directly stored coordinates in Rect object. I tried template matching there it directly stores the matched template region to another Mat object. But I want those coordinates for further detection of object in this area of interest. So do you know any way I can do this?

Ya I do understand the difference. What I wanted to do is Detected rectangular region coordinates of an image to be stored in Rect.

Can I use Converters class methods for what you have told? What does the following method does public static void Mat_to_vector_Rect(Mat m, java.util.List<rect> rs)? Could you also explain me about the second argument in this method?

I want to store Mat object values in Rect object. To do that I tried to create MatOfRect object with Mat Object values. But it throws an Exception saying Incompatible Mat and then app stops. Can anybody help me to solve this?What am I doing wrong?

I want to use external webcam in my android project. But I don't know how to obtain the index of external webcam, so that I can use it in SetCameraIndex() of CamerabridgeViewBase object. How can I do it?

Please someone answer my question.

I want to use external webcam in my android project. How can I set the index of external webcam in opencv camerabridgeviewbase. How can I get the index of external camera?
