2013-08-23 04:18:57 -0600	asked a question	What is the non-free functions in opencv? http://docs.opencv.org/modules/nonfree/doc/nonfree.html ok, I got some function which is non-free. So, now what? Do I need to pay the license fee to them? Or I need to mark in on my application? What should I do?
2013-08-09 06:37:49 -0600	commented question	Build Error for OpenCV Java 2.4 on Linux I got the same issue. Hope someone can help. But here is my config: OS X 10.8.4 Java(TM) SE Runtime Environment (build 1.7.0_25-b15) cmake version 2.8.11.2 Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode) Python 2.7.2 (default, Oct 11 2012, 20:14:37) Apache Ant(TM) version 1.9.2 compiled on July 8 2013

2013-08-02 06:35:02 -0600	asked a question	What is the best object detection scale? I am using the `SurfFeatureDetector` to do object detection. But I find that the object's image size will affect the object detection's result. For example, if my object image is very large, it can't successfully detect, or too small can't successfully detect also. So, my question is, Is there any detector will ignore the image size? or How can I do to increase the success rate? Thanks.
2013-08-01 04:58:32 -0600	commented answer	How to get the findHomography result's position relative to scene? But what is this line for: float roatation = acos( H.at<double>(0,0)) * 180/CV_PI;
2013-07-31 07:53:04 -0600	asked a question	How to get the findHomography result's position relative to scene? I follow the following tutorial: http://docs.opencv.org/doc/tutorials/features2d/feature_homography/feature_homography.html#feature-homography And I can detect the object I want. But I would like to know the position, and the coordinate is relative in the scene image. And I take the source code's `scene_corners` vendor, but the position is totally wrong. How can I transfer it the the right position? Thanks.
2013-06-30 18:42:31 -0600	commented question	Features2D + Homography example doesn't work Sometime, I find that the image size does matter. I still don't have idea yet. But my experience is, if the object you want to find is too big. You can't find anything, after I resize the object, sometime, the success rate will be higher. But I still finding the reason.

2013-06-30 00:58:37 -0600	asked a question	About the tutorial of finding image using Features2D + Homograph in openCV http://docs.opencv.org/doc/tutorials/features2d/feature_homography/feature_homography.html I download this tutorial source code, and try to play around the the openCV. I use a smile face to test the programme. And the first testing is a screen shot from my computer: It success and find the smile face. But the other test is using a real life example like this: But this time, the smile face can't be detected. The match result like this: If I wanna to modify the programme to let it detect the smile face in real life pic. What should I do? Any suggestions? Thanks.
