2014-04-09 14:16:50 -0600 | answered a question | BlackBerry 10 and Momentics IDE There are Step-by-Step instructions provided here. |
2014-04-09 09:44:08 -0600 | asked a question | BlackBerry 10 and Momentics IDE Hello, Are there any Step-by-Step Tutorials that make openCV functions availible from within a "Blackberry-Cascades-Project" created inside the Momentics IDE on a Windows 7 64-bit machine? I already found HelloOpenCV, but i do not have "make" and "qcc" on Windows 7 64-bit. I tried to install make and then the Momentics IDE showed me an error "cannot find qcc". I know that it is something like a compiler... Secondly, i also found Blackberry OpenCV, but there is no explanation on how to integrate everything within the Momentics IDE and a Cascades-project. I am used to getting things done in Java and i do understand the concept of importing libraries from the Java perspective. I found a Visual Studio Tutorial and wanted to ask if it is possible to use this to configure the Momentics IDE? |

The website used in the cite is: http://opencv.willowgarage.com/documentation/cpp/saturation_arithmetics.html Does someone know the author ? |

2013-05-22 09:30:16 -0600 | answered a question | how do i create a runnable jar that use opencv You must supply the c++ dll AND the openCV-jar to the jar file at jar creation time. Although i am not sure how to do it, i am sure about that this is the error, because the same error happens when forgetting to add the dll to the classpath. |

2013-05-18 07:31:12 -0600 | asked a question | read smaller Mat 'pixel by pixel' while sliding over bigger Mat I want to read a fixed-size-submat from a bigger Mat while sliding it over the bigger one pixel by pixel (or maybe 5 pixel by 5 pixel or somtheing like that, i hope you get the idea). Is there a predefined function for that in openCV, if so which one is it? (Besides i am using Java with opencv 2.4.5..) I have an idea how to write it myself in java using Mat.submat(a,b,c,d), but i thought that the underlying c++ dll implementation would be a lot faster. |

2013-05-02 07:10:07 -0600 | commented question | calculating and drawing histogram in java with opencv Thanks for the side-note that it should be easy to adapt. |
2013-05-02 05:32:45 -0600 | asked a question | calculating and drawing histogram in java with opencv I have read the Tutorial on calculating and drawing histograms in c++. Unfortunately, i couldn't find the "histImage()"-method inside the Java API. Do I have to write a Histogram-function from scratch or has somebody experience with java openCV and could point me in the right direction respectively point to the corresponding methods in the java API. |
2013-05-02 05:12:28 -0600 | commented answer | png compression yep i found it out |
2013-05-02 02:35:42 -0600 | marked best answer | png compression Why does the png-file-size increase? Here is the code (in Java): Initially the "img1.png"-file is 900kb, but "img1out.png" becomes 2200kb! I have read that the compression in openCV is not as good as in other image-processing API's, but recently some compression has been added. I tried out to do this here: But the size still goes up to 2200kb of "img1out.png". What am i doing wrong here ? |
2013-05-02 02:35:37 -0600 | commented answer | png compression Actually i had to instantiate the "compression-vector" like this "MatOfInt mPngCompressionRate = new MatOfInt(Highgui.CV_IMWRITE_PNG_COMPRESSION,0);" gives 5000kb and "MatOfInt mPngCompressionRate = new MatOfInt(Highgui.CV_IMWRITE_PNG_COMPRESSION,9); gives 2000kb". (poor javadoc) |
