2014-01-08 09:07:28 -0600 | commented answer | Adding row to Mat in Java Yes, that's true. Unfortunately MatOfFloat while using dump() outpust e.g. [1,2,3] and it's size 1x3, co it is confusing. I did have to transponse it first. |

2014-01-07 15:39:01 -0600 | asked a question | Adding row to Mat in Java I have a problem with adding rows to Mat. I use push_back method but I get error: Sizes of input arguments do not match. Of course my Mats have same column length as it is said in method description. ^It will result in error which I described above. Do you have any ideas how insert a row to a matrix? |

2013-11-12 17:42:53 -0600 | commented question | HOG compute jni error A minute ago I checked that it falls when I have image files and folder in the same input folder(with samples) so it seems that is the issue (my bad). Thank you for your quick answer:) |
2013-11-12 17:27:16 -0600 | commented question | HOG compute jni error As you wish ^ These are standard parameters for HOG. I tried different combinations of parameters but I stillget jni error. |

2013-11-12 16:58:10 -0600 | asked a question | HOG compute jni error I use java version of opencv and I want to compute HOG by using hog.compute. The problem is that I get: java.lang.Exception: Unknown exception in JNI code {objdetect::compute_10()} at org.opencv.objdetect.HOGDescriptor.compute_0(Native Method) I would be grateful if someone could help.

2013-03-28 18:33:55 -0600 | commented answer | Desktop Java - how to load video file? It would be nice if more Highgui package method were implemented in Java version. It is quite irritating (and not very efficient) when you have to use other libraries and solutions to make it work. |
2013-03-28 09:37:09 -0600 | commented answer | Desktop Java - how to load video file? It seems it's the only way to do it. Thanks for your time:) |
2013-03-28 09:20:26 -0600 | commented answer | Desktop Java - how to load video file? You can't pass parameter of a different type in Java. Method open is not applicable for String type parameter, it won't compile. That's the problem of this package;/ I can read camera input, get frames, save them etc. But still can't open a video file;/ |
2013-03-28 08:50:31 -0600 | commented answer | Desktop Java - how to load video file? oc I read this example, but there is no method that takes a filename, stream as a parameter. Method open takes only int id, and it's a device id (camera). If you managed to open a video file using this package I would be grateful for example. |
2013-03-28 08:21:51 -0600 | commented answer | Desktop Java - how to load video file? Thanks for reply:) I have found VideoCapture package, but it doesn't have method (like cvCapturefromAvi), you can only open a stream from a camera (method takies int parameter of a device, not a file name). If I misunderstood something I' sorry;) |
