Currently I am working on a project that will involve:
-detecting faces
-recording when a face is detected
-stop recording when a face is detected
-replay this footage with the face removed
Right now I have a base code that accomplishes deleting the face by using a copy of the image stored (background image) when the space bar is hit. However, I need to have it record the face in video, then replay it, and this action triggered by the detection of a face. Any suggestions of how to go about doing this? Also, I know that there is a way to change the size of the rectangle placed around the face detected, but how do I go about doing that? I've done it before in simpler programs, but I can't seem to do it now. This project will be used for a video installation.
current code is:
// This program takes a single image when you press any key (background image)
// it then detects faces and replaces the face area with
// the background image
opencv = new OpenCV(this);
opencv.capture( 320, 240 );
// face recognition
opencv.cascade( OpenCV.CASCADE_FRONTALFACE_ALT ); // load the FRONTALFACE description file
}
void draw() {
opencv.read();
// display the current video feed
image( opencv.image(), 0, 0 );
// detect anything ressembling a FRONTALFACE
Rectangle[] faces = opencv.detect();
// draw detected face area(s)
fill(255,0,0);
stroke(255,0,0);
for( int i=0; i<faces.length; i++ ) {
// copy a specific area from the image in memory (the background)
// place the copy exactly where the face is in the current image
rectMode(CENTER);
copy(opencv.image(OpenCV.MEMORY),faces[i].x,faces[i].y,faces[i].width,faces[i].height,faces[i].x, faces[i].y,faces[i].width,faces[i].height);
}
// display the image in memory
image( opencv.image(OpenCV.MEMORY), 329, 0 );
}
// When a key is pressed, capture the background image
void keyPressed() {
opencv.remember(); // store the actual image in memory
}
