2014-02-27 23:29:05 -0600 | asked a question | Histogram Equalization of color image Open CV SDK for java! Dear Folks, I am working on an image processing app in android and I am trying to achieve Histogram equalization for color image. I could able to get it done for grey scale image since it has only one channel . Now I need to do it for color image where number of channel is more! Some one please guide me how do I proceed and I want to do in '.java' file using opencv sdk api, Imgproc.equalizeHist(src, dst) since few of the method in native is not working for me ! Thats why I am shifting to java ! Thanks in advance NSM |
2014-02-26 08:21:59 -0600 | commented question | calcHist method Inavalid Arguments. @berak I agree. But compiler for 32 bit and compiler for 64 bit would be different right . So you mean to say the 32 bit compiler only throwing this error ? Do I need to check with different compiler combination for 32 bit ? Am I missing any configuration changes ? Please guide me! |
2014-02-26 08:10:46 -0600 | commented question | calcHist method Inavalid Arguments. @berak if I run the same code in 64 bit machine , it compiles without error! I am wondering what I may be missing! |

2014-02-26 07:19:42 -0600 | asked a question | calcHist method Inavalid Arguments. Dear Folks, I am trying to find histogram in the image and I am trying to use calcHist method like below calcHist( &bgr_planes[0], 1, 0, Mat(), b_hist, 1, &histSize, &histRange, uniform, accumulate ); I am trying this example from the link http://docs.opencv.org/doc/tutorials/imgproc/histograms/histogram_calculation/histogram_calculation.html All the time I am getting this error and I am not able to compile the code "Invalid arguments ' Candidates are: void calcHist(const cv::Mat *, int, const int *, const cv::_InputArray &, cv::SparseMat &, int, const int *, const float * *, bool, bool) void calcHist(const cv::Mat *, int, const int *, const cv::_InputArray &, const cv::_OutputArray &, int, const int *, const float * *, bool, bool) void calcHist(const cv::_InputArray &, const std::vector<int,std::allocator<int>> &, const cv::_InputArray &, const cv::_OutputArray &, const std::vector<int,std::allocator<int>> &, const std::vector<float,std::allocator<float>> &, bool) '" I have configured my build c/c++ build path with the required includes I am working on 32 bit system and have set up appropriate NDK for windows 32 bit system. Same code when I run on 64 bit system where the method compiles without any issue! Really Banging my head since morning . Some one pleeeeaaase help :(:) Edited: Mat imagMat=cvLoadImageM("/sdcard/ImageProcessing/TestImage.png"); LOGD("Number Of Rows = %d",imagMat.rows); Thanks in Advance NSM |
