2016-04-28 10:37:09 -0500 commented question Which is the easy and robust method for eye blink detection?

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

2016-04-28 10:10:03 -0500 commented question Which is the easy and robust method for eye blink detection?

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

2016-04-28 10:04:27 -0500 commented question Which is the easy and robust method for eye blink detection?

Yes I am able to detect eyes at the moment.

2016-04-28 09:53:15 -0500 asked a question Which is the easy and robust method for eye blink detection?

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?

2016-04-25 21:15:41 -0500 asked a question What is the use of numpy library in opencv python?

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.

2016-04-23 23:49:58 -0500 asked a question Why calculated Fps is more than the actual Fps?

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.

2016-04-21 04:39:29 -0500 asked a question How to calculate Frames per second?

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?

2016-04-19 03:05:26 -0500 commented question Can any body tell me how to intialize MatOfRect object with MatOfRect Constructor taking Mat object as a parameter?

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?

2016-04-19 02:19:48 -0500 commented question Can any body tell me how to intialize MatOfRect object with MatOfRect Constructor taking Mat object as a parameter?

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

2016-04-19 01:50:08 -0500 commented question Can any body tell me how to intialize MatOfRect object with MatOfRect Constructor taking Mat object as a parameter?

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?

2016-04-19 00:19:20 -0500 asked a question Can any body tell me how to intialize MatOfRect object with MatOfRect Constructor taking Mat object as a parameter?

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?
