Hi all. I am new here and with processing, but wanna get more skills on it. So I wanna ask maybe you know where I get good demos or code for detect (faces, colors, objects) programs. I try some code for face detect but get error with java. My code after 2-3 min working stop. Code is easy but I no idea from where get fatal java error.
Code using OpenCV libaries;
import hypermedia.video.*;
import java.awt.Rectangle;
OpenCV opencv;
// contrast/brightness values
int contrast_value = 0;
int brightness_value = 0;
void setup() {
size( 320, 240 );
opencv = new OpenCV( this );
opencv.capture( width, height ); // open video stream
opencv.cascade( OpenCV.CASCADE_FRONTALFACE_ALT ); // load detection description, here-> 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" );
}
public void stop() {
opencv.stop();
super.stop();
}
void draw() {
// grab a new frame
// and convert to gray
opencv.read();
opencv.convert( GRAY );
opencv.contrast( contrast_value );
opencv.brightness( brightness_value );
Hi all. I always get like this error after my program work 1-2 min :

My comands list are working on face detection with OpenCV libraries. I need somehow to fix that because I wanna connect with arduino mainbord which will control camera movements by 2 servo motors. Event like this example get this errors :
// contrast/brightness values
int contrast_value = 0;
int brightness_value = 0;
void setup() {
size( 320, 240 );
opencv = new OpenCV( this );
opencv.capture( width, height ); // open video stream
opencv.cascade( OpenCV.CASCADE_FRONTALFACE_ALT ); // load detection description, here-> 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" );
}
public void stop() {
opencv.stop();
super.stop();
}
void draw() {
// grab a new frame
// and convert to gray
opencv.read();
opencv.convert( GRAY );
opencv.contrast( contrast_value );
opencv.brightness( brightness_value );
