I am currently working on an interactive mosaic mirror.

At the moment i have the code, taking in the live video feed and detecting the light and dark sections of the capture. and displaying large squares for light and smaller squares for dark.

I am now intrested in replacing these squares with images from a selected folder. Dose anyone have any advice and ideas on how i would go about this.

Thanks.

Code so far...

Code:

// interactive miror

// Each pixel from the video source is drawn as a
// rectangle with size based on brightness.

import processing.video.*;

// Size of each cell in the grid
int videoScale =10;
// Number of columns and rows in our system
int cols, rows;
// Variable for capture device
Capture video;

void setup() {
 size(740,580);
 // Initialize columns and rows
 cols = width/videoScale;
 rows = height/videoScale;
 smooth();
 // Construct the Capture object
 video = new Capture(this,cols,rows,15);
}

void draw() {
 if (video.available()) {
   video.read();
 }
 background(0);

 video.loadPixels();

 // Begin loop for columns
 for (int i = 0; i < cols; i++) {
   // Begin loop for rows
   for (int j = 0; j < rows; j++) {

     // Where are we, pixel-wise?
     int x = i*videoScale;
     int y = j*videoScale;

     // Reversing x to mirror the image
     // In order to mirror the image, the column is reversed with the following formula:
     // mirrored column = width - column - 1
     int loc = (video.width - i - 1) + j*video.width;

     // Each rect is colored white with a size determined by brightness
     color c = video.pixels[loc];

     // A rectangle size is calculated as a function of the pixel's brightness.
     // A bright pixel is a large rectangle, and a dark pixel is a small one.
     float sz = (brightness(c)/255.0)*videoScale;
     rectMode(CENTER);
     fill(255);
     noStroke();
     rect(x + videoScale/2,y + videoScale/2,sz,sz);

   }
 }
}  

Yeah I thought my best bet would be binding certain images to set brightness values, but i have no idea how i would go about doing so.

I have tired a basic if statement, but no luck yet.
Any ideas?
