    <p>Im using opencv 2.4.4 and I want to detect and track face with java. I found the example as follow in internet.</p> <p>example </p> <pre><code>import hypermedia.video.*; import java.awt.Rectangle; float last = millis(); float interval = 100; int startTime; int noFaces = 0; int noFacesPrev = 0; int dx = 0; int dy = 0; int dwidth = 400; int dheight = 400; OpenCV opencv; // contrast/brightness values int contrast_value = 0; int brightness_value = 0; void setup() { size( 800,800 ); opencv = new OpenCV( this ); opencv.movie( "egypt.mov", 320, 240 ); // load movie file opencv.cascade( OpenCV.CASCADE_FRONTALFACE_ALT ); // load detection description, here-&gt; front face detection : "haarcascade_frontalface_alt.xml" // print usage println( "Drag mouse on X-axis inside this sketch window to change contrast" ); println( "Drag mouse on Y-axis inside this sketch window to change brightness" ); } void stop() { opencv.stop(); super.stop(); } void draw() { // grab a new frame opencv.read(); opencv.contrast( contrast_value ); opencv.brightness( brightness_value ); // proceed detection Rectangle[] faces = opencv.detect( 1.2, 2, OpenCV.HAAR_DO_CANNY_PRUNING, 40, 40 ); // 40,40 is the smallest size its looking for // draw face area(s) noFaces = faces.length; if (faces.length &gt;=1 &amp;&amp; noFaces &gt; noFacesPrev) { startTime = millis(); println(startTime); println(noFaces); println(noFacesPrev); noFacesPrev = noFaces; } if (faces.length == 0) { // if there is no face, start over println("no face"); startTime = 0; noFacesPrev = 0; } if (startTime &gt; 0) { println("started"); if(millis() - startTime &gt;interval &amp;&amp; (faces.length &gt;=1)) { for ( int i = 0; i= 800){ dy = dy+400; dx = 0; } if (dy &gt;= 800){ dy = 0; dx = 0; } } startTime=0; println ("clock reset"); noFacesPrev=0; } } } // Changes contrast/brigthness values void mouseDragged() { contrast_value = (int) map( mouseX, 0, width, -128, 128 ); brightness_value = (int) map( mouseY, 0, width, -128, 128 ); } void keyPressed() { if (key == 's') { opencv.stop(); super.stop(); } } </code></pre> <p>When I want to try this code in my project, I cannot initialize "<code>OpenCV opencv;</code>" !! also, I cannot import "hypermedia.video" !</p>

    1. COCan you post a link to where "in internet" you found the example? Did you make sure `hypermedia.video` is in your classpath? How should Java know what `OpenCV` class to instantiate?

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.
