问题 This question is related to my previous question in that question I used color image as input and it identify by using line color but I like to know how to identify that kind of image using gray-scale image. This is the gray-scale input image and have to identify And I need to identify following objects with its positions (x and y coordinates). Please can some one explain with simple code example to identify those objects and I need to identify connected lines of those objects as well (As

问题 I have an IplImage that I converted in a Matrix, and now I want to iterate cell by cell. CvMat mtx = new CvMat(iplUltima); for (int i = 0; i < 100; i++) { //I need something like mtx[0][i] = someValue; } 回答1: ¡¡I DID IT!! I share it: CvMat mtx = new CvMat(iplUltima); for (int i = 0; i < 100; i++) { for (int j = 0; j < 100; j++) { opencv_core.cvSet2D(mtx, i, j, CvScalar.ONE); } } iplUltima = new IplImage (mtx); Where i = row and j = column 回答2: First, you need to import the following from

问题 I'm doing a project that use image processing techniques to identify different objects and their lengths. I go through many examples in javaCV as well as OpenCV. But unfortunately I was unable to identify T shape of polygon. I try to use following rectangle identification method but I failed it. public static CvSeq findSquares( final IplImage src, CvMemStorage storage) { CvSeq squares = new CvContour(); squares = cvCreateSeq(0, sizeof(CvContour.class), sizeof(CvSeq.class), storage); IplImage

问题 I had this piece of code to be converted into Java using OpenCV4Android. But their are no Java-Wrappers for matiterator in OpenCV4Android. void show_result(const cv::Mat& labels, const cv::Mat& centers, int height, int width) { std::cout << "===\n"; std::cout << "labels: " << labels.rows << " " << labels.cols << std::endl; std::cout << "centers: " << centers.rows << " " << centers.cols << std::endl; assert(labels.type() == CV_32SC1); assert(centers.type() == CV_32FC1); cv::Mat rgb_image

问题 I have searched for the solution and found - Java CV - FFmpeg Need step by step to integrate them like this 回答1: Steps for Integrating FFMPEG (1.) Download ffmpeg from here: http://bambuser.com/opensource. It contains scripts to build ffmpeg for android. (2.) Modify build.sh. Replace "com.bambuser.broadcaster" with your package name. You also need to set the ffmpeg flags to enable to codecs you're interested in. (3.) Run build.sh, and copy the build/ffmpeg directory into your apps jni/lib

问题 I'm java developer .My goal is to detect image keypoints using javaCV this is my code : final CvMat image1 = cvLoadImageM("im1.png" , 0); final CvMat image2 = cvLoadImageM("im2.png", 0); SIFT sift = new SIFT(); FeatureDetector featureDetector =sift.getFeatureDetector(); KeyPoint keypoint1 = new KeyPoint(); KeyPoint keypoint2 = new KeyPoint() ; featureDetector.detect(image1, keypoint1 , null); featureDetector.detect(image2,keypoint2, null); but when I run this code I got an access violation
