    <p>This code is OpenCV c++:</p> <pre><code>lines = cvHoughCircles(frame2, storage, CV_HOUGH_GRADIENT, 1, 50, 300, 60, 10, 600); for (int i = 0; i &lt; lines.total(); i++) { //Would like the code to go here CvPoint2D32f point = new CvPoint2D32f(cvGetSeqElem(lines, i)); cvCircle(src, cvPoint((int)point.x(), (int)point.y()), 3, CvScalar.WHITE, -1, 8, 0); Point p = new Point((int)point.x(), (int)point.y()); points.add(p); } </code></pre> <p>What is the correspondent in the new Java Api? I cannot get <code>CvPoint2D32f</code>, <code>cvGetSeqElem</code> and <code>CV_AA</code>. I found that existed in JavaCV but cannot find them in OpenCV Java api.</p> <p>Thanks</p> <p><strong>EDIT:</strong></p> <p>I've changed my code and now I have:</p> <pre><code>MatOfPoint3 circles = new MatOfPoint3(); Imgproc.HoughCircles(image, circles, Imgproc.CV_HOUGH_GRADIENT,2, image.rows()/4,200,100,0,0); for(Point3 circle : circles.toArray()){ Point center = new Point(circle.x, circle.y); int radius = (int) Math.round(circle.z); Core.circle(image, center, radius, new Scalar(0,255,0), 6, 8, 0); } </code></pre> <p>However I got an error at <code>for(Point3 circle : circles.toArray())</code>:</p> <pre><code>Exception in thread "main" java.lang.UnsupportedOperationException: Mat data type is not compatible: 21 at org.opencv.core.Mat.get(Mat.java:2581) at org.opencv.core.MatOfPoint3.toArray(MatOfPoint3.java:64) at org.opencv.core.MatOfPoint3.toList(MatOfPoint3.java:76) at main.java.DetectFaceDemo.run(HelloOpenCV.java:60) at main.java.HelloOpenCV.main(HelloOpenCV.java:83) </code></pre> <p>Any thoughts on this? Thanks</p> <p><strong>EDIT 2:</strong></p> <p>The solution to last edit problem resides in <code>MatOfPoint3 circles = new MatOfPoint3();</code></p> <p>It must be <code>MatOfPoint3f circles = new MatOfPoint3f();</code></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
