please format code with </> button * homework policy * asking questions
I am new to processing and am having trouble creating code. I’m using a face detector, but instead of a square I want the face to pixel that area of a video. I have made a code but the pixels do not appear, how can I solve it? Thanks a lot!
Modified the code but I get a black square, I think it’s a color problem, can someone fix it? Specifically this part:
for (int i = 0; i < faces.length; i++) {
//println(faces[i].x + "," + faces[i].y);
float d = dist(faces[i].x, faces[i].y, faces[i].width, faces[i].height);
numPixelsWide = faces [i].width;
numPixelsHigh = faces[i].height;
println(numPixelsWide);
movColors = new color[numPixelsWide * numPixelsHigh];
film.read();
film.loadPixels();
for (int j = 0; j < numPixelsHigh; j++) {
for (int r = 0; r < numPixelsWide; r++) {
fill(movColors[j*numPixelsWide + r]);
I put the full code too:

opencv.loadCascade(OpenCV.CASCADE_FRONTALFACE);
cam.start();
film.loop();
noFill();
}

//scale(2);
opencv.loadImage(cam);
//video.loadPixels();
image(film, 0, 0);
loadPixels();
Rectangle[] faces = opencv.detect();
if (frameCount%15==0) println(faces.length);
for (int x = 0; x < film.width; x++) {
for (int y = 0; y < film.height; y++) {
// Calculate the 1D location from a 2D grid
int loc = x + y * film.width;
float h= hue(film.pixels[loc]);
float s= saturation(film.pixels[loc]);
float br= brightness(film.pixels[loc]);
for (int i = 0; i < faces.length; i++) {
//println(faces[i].x + "," + faces[i].y);
float d = dist(faces[i].x, faces[i].y, faces[i].width, faces[i].height);
float adjustbrightness = map(d, 50, 200, 0, 255);
color c = color(h, s, br);
}
}
