Unexpected token: void()

  First of all you need to learn to format your code for this forum. Look here

  There are several errors in your code. The first is in line 8 where the statement int i = 0 needs a semicolon

  Then the variables sumar, sumag and sumab are declared local to the for loop and have not been initialised before use.

  Then you have extra unneeded )

  The corrected code looks like

  import processing.video.*;
  Capture webcam;
  int w=400;
  int h=400;
  int pixn=w*h;
  int keyhits;
  PImage img;
  int i= 0;
  
  
  void setup() {
    size(w, h);
    webcam = new Capture(this, 400, 400);
    webcam.start();
    loadPixels();
  }
  
  void captureEvent(Capture webcam) {
    webcam.read();
  }
  void draw() {
    image(webcam, 0, 0);
  }
  
  void keyPressed() {
  
    if ( key == '1' ) {
      save("capture" + ++keyhits + ".jpg");
    }
  
    img = loadImage("capture"+keyhits+".jpg");
    int x = int(img.width);
    int y = int(img.height);
    float r = red(img.pixels[i]);
    float g = green(img.pixels[i]);
    float b = blue(img.pixels[i]);
    float sumar = 0, sumag = 0,  sumab = 0;
    for (int i=0; i<pixn; i++) {
      sumar = sumar + red(img.pixels[i]);
      sumag = sumag + green(img.pixels[i]);
      sumab = sumab + blue(img.pixels[i]);
    }
  
    float mediar = sumar / pixn;
    float mediag = sumag / pixn;
    float mediab = sumab / pixn;
  
  
    if ( key == '2' ) {
      fill(mediar, mediag, mediab, 255);
      rect(0, 0, 400, 400);
      save("average_color"+ keyhits + ".jpg");
    }
  }

  And you haven't formatted the code properly.
