Hi im trying to save effects to an image using a webcam, but it only saves the webcam image without the effects, anyone know if it's possible and what code to use if so?

Hey all, I am writing some code that will get OSC messages from supercollider and use that to control some whitney-esque visuals. Originally i took some code from KrazyDad that was a processing transcription of the code present in Whitney's book Digital Harmony. The trouble comes with the lines of code referencing ftime -> which is the amount of time the frame has been running. the code from crazy dad uses millis to control ftime, and i added a modulo to that make an infinite loop of the visuals within set bounds. I am trying to move away from the infinite aspect of it using a for loop to supply the ftime values, however, when i use the loop it does not display the visuals in the same way. I will post the broken code, any help would be appreciated.

import oscP5.*;
import netP5.*;

//Create OSC variable
OscP5 oscP5;

//Create variable to use as OSC trigger for animation
boolean animate = true;

//First step of animation
float stepstart = -1,
//Last step of animation
      stepend = 1,
      radius,
//X and Y Centers
      xcenter,
      ycenter,
//Speed of animations 
      speed = .1;

//Degree to radian multiplier
float deg = 0.0174533;

//Number of points in the animation
float  npoints = 500.0;

void setup()
{
  size(1000,1000);      //Size of window
  radius = height*.9/2;  
  xcenter = width/2;
  ycenter = height/2;
  oscP5 = new OscP5(this,7771);
  noStroke();
}

void draw()
{
  background(0);
  fill(255);
  stroke(255);  
  if (animate == true){   
    whitney(1); 
  }else{
  } 
}

void whitney(int runs){
//  float ftime = ((millis()*0.0001)%1);    k replaces ftime
for (int j = 0; j < runs; j++){
for (float k = 0; k < 1; k += 0.001){
  float step = stepstart + (k * (stepend - stepstart));
  println("ftime = " + k + "    step = " + step);
  //Calculates the position of each point based on the current step
  for (int i = 0; i < npoints; ++i)
     {
     float points = 360 * (i/npoints);
     float a = 2*PI* points * deg;
     float radiusi = radius*cos(a*step);
     float x = xcenter + cos(a) * radiusi;
     float y = ycenter + sin(a) * radiusi;
     ellipse((int) x, height-(int) y, 2+k,2+k);
     line(x,y,x+1,y+1);
     }
}
}
}


void oscEvent(OscMessage theOscMessage){
  //store the int from the OSC message in msg
  int msg = theOscMessage.get(0).intValue();
  
  if (msg == 1){
    animate = true;
  }else if (msg ==2){
    animate = false;
  }
  if (msg == 3){
    stepend = 5;
    stepstart = 5;
  }else if (msg == 4){
    stepend = 6;
  }

}

Does anybody of you know how can be done the equalization histogram and the descrete case histogram for a given image?
