I'm trying to record a video in Android using the JavaCV lib. I need to record the video in 640x360. I have installed everything as described in README.txt file and I followed the example as below: https://code.google.com/p/javacv/source/browse/samples/RecordActivity.java In this example, the video size is this: private int imageWidth = 320; private int imageHeight = 240; In my case, I need to record a video in 640x360 H.264. (UPDATE) I have reverted my code and kept exactly like in the example, just changing imageWidth and imageHeight to 640x360. Now I'm getting the video like this image:

Please can some one explain about cvFindContours method and what are the parameters that it required? For example, here's code using OpenCV: hierarchy = cv2.findContours(thresh, cv2.RETR_LIST, cv2.CHAIN_APPROX_SIMPLE) Please can some one explain how to write this using JavaCV? As comments mentioned by Mohammad those three parameters are header_size , mode and method . You can use this method as follows IplImage src = cvLoadImage(path);//hear path is actual path to image IplImage grayImage = IplImage.create(src.width(), src.height(), IPL_DEPTH_8U, 1); cvCvtColor(src, grayImage, CV_RGB2GRAY);

I am trying to learn JavaCV. As you all know, the lack of educational materials on this subject is a very big problem. In JavCV home page, they have provided lot of examples for the C++ examples in book "OpenCV CookBook". But the case is, they are not Java, they are in SCALA!!!! Now I have already gone crazy! I know lot of examples are in web, but I want to learn it from beginning to advance, then only I can do it properly. "OpenCV CookBook" is a very good book but it is all about OpenCV in C++, not anything about Java. Someone please help me to find a better place to learn JavaCV. Provide me

I am trying to stitch a large number of images which have good amount overlap like these: ExampleImage1 and ExampleImage2 . Firstly, i want a 1D line of a grass patch. Something like this: Result . This is a screenshot of the original result, the original picture is more than 2MB. Hence couldnt upload it. This was achieved by breaking down 300 images into small sets and stitching them. Like this example but in a larger scale with more heirarchies - 0.jpg,1.jpg,2.jpg images in stitch1.jpg, 2,3,4 in stitch2.jpg and later stitching stitch1.jpg and stitch2.jpg together Now i want to get the same

I have made a application to grab video from a webcam and detect motion using OpenCV and JavaCV. I am trying to export as an executable jar using eclipse. The program runs fine in eclipse as does the exe jar on the computer I coded the program on. What I am trying to accomplish is to make the exe Jar run on computers that don't have OpenCV installed. Basically what I would consider a portable application. When I run the exe jar on a different computer that has nothing installed other than the JRE I get unsatisfied link errors seen below. Exception in thread "Video Thread" java.lang

I've been attempting to install NativeScript with Angular with this tutorial for the past two days, and I keep running into problems surrounding the Android SDK not installing correctly and freezing, and finally re-installing the latest JDK and JVE before attempting to install Android Studio. As I researched the problem I think I found the culprit: When I run Javac -version I keep getting an older version of JDK, it states: javac 1.6.0_45 However I have the latest version of Jdk 1.8.0_102. I researched the problem, but only found either complex solutions invilving the variable path, or MAC
