Question

第一个问题在这里。我找到了这个视频： https://youtu.be/V2wDl_takes

有人知道他怎么做的吗？谢谢。

我有一个正在使用的单词数据表，并且正在使用具有Java处理功能的网络摄像头来制作与此类似的内容。
他把像素变成文字了吗？
他使用字符串值还是数据？图像处理？

到目前为止的代码：

import processing.video.*;

//import camera3D.*;
//import camera3D.generators.*;
import camera3D.generators.util.*;

float x;
float y;

Capture cam;
int switcher = 0;

PFont font;
String message = "";
PImage words1, words2, words3, words4, words5, words6, words7; 

void setup(){
  size(640, 480);
  font = createFont("Arial",20,true); 
  //size(1920,1200); 

  stroke(0); 
  words1 = loadImage("words1.PNG");
  words2 = loadImage("words2.PNG");
  words3 = loadImage("words3.PNG");
  words4 = loadImage("words4.PNG");
  words5 = loadImage("words5.PNG");
  words6 = loadImage("words6.PNG");
  words7 = loadImage("words7.PNG"); 

  cam = new Capture(this, 640, 480);
  cam.start();
}

void draw(){
   loadPixels();
   filter(GRAY);
   text("You are loved",0,0);
   textAlign(CENTER);
   textFont(font);
   //translate(width/2,height/2);


 float newx = constrain(x + random(-20, 20), 0, width);   
  float newy = constrain(y + random(-20, 20), 0, height-1);

  // Find the midpoint of the line
  int midx = int((newx + x) / 2);
  int midy = int((newy + y) / 2);
  // Pick the color from the video, reversing x
  color c =pixels[(width-1-midx) + midy*width];

  // Draw a line from (x,y) to (newx,newy)  
  stroke(c);  
  strokeWeight(4);  
  line(x, y, newx, newy);  

  // Save (newx,newy) in (x,y)  
  x = newx;  
  y = newy;
  if (cam.available()){
    cam.read();

  int skip = 20;
  for (int x = 0; x < words1.width; x+=skip) {
    for (int y = 0; y < words1.height; y+=skip) {

      int index = x + y * words1.width;
      float b = brightness(words1.pixels[index]);
      float z = map(b, 0, 255, 250, -250);
      fill(255-b);
      pushMatrix();
      popMatrix();
  }
  }

  //String[] words = { "apple", "bear", "cat", "dog" };
//int index = int(random(words.length));  // Same as int(random(4))
//println(words[index]);  // Prints one of the four words

if(switcher==0){
    image(cam,0,0);
  }
  else if(switcher == 1){
    scale(-1,1);
    image(cam,-width,0); 
  }
  else if(switcher == 2){
    scale(-1,-1);
    image(cam,-width,-height);
  }
  else{
    println("Switcher = 0 again");
    switcher = 0;
  }
}
}```

使用网络摄像头输入进行实时排版处理
