Maestro 0.5b

Published by Michael Doyle under JMyron, MIDI, Processing, controlP5, ess r2

I've given another last shot to the piano, it's working now. I removed proMIDI from it and implented ess r2, however, i don't have time to work on it anymore. I'm finishing the final report at the moment.

I've revisted version 1.1 as the 1.2's Sine class is making it difficult to add on to at the moment. So, 1.1b is changing the pitch of a sine wave on the Y axis and changing the pitch of a triangle wave on the X axis. Here is the code:

Tracking pixels

Published by Michael Doyle under JMyron, Processing, controlP5, ess r2

For testing purposes, I have added the tracking of the pixels of a certain value and the average point of these. This allows me to grab the x and y co-ordinates of the average point an, hopefully, work the ess prototype around it.

    Updated this to now include:

    • Finds the average point of all blobs and places a marker where it is
    • Outputs the amount of Globs detected for the clicked color value

    So after playing around with it,  I have to say it's working quite well. It's come on a long way from what I started with. I now have to concentrate on the ellipse and look at how I can track that to manipulate the pitch of sine waves and start hit tests with buttons.

    JMyron + controlP5 iteration #5

    Published by Michael Doyle under JMyron, Processing, controlP5

    Got everything working great. I did a step around the mouse click problem. To select a color, a double click is needed.Since only one click is needed to drag the sliders in controlP5, it won't invoke the mouse event method.

    So, at the moment, this iteration allows a user to:

    • Double click the video feed to track a color
    • See the RGB value of their chosen color
    • See the x,y co-ordinates of their mouse click
    • Set the sensitivity of the color tracking
    • Set the max/min amount of pixels to detect

    Here is the code:

    1. import JMyron.*;

    JMyron + controlP5 iteration #4

    Published by Michael Doyle under JMyron, Processing, controlP5

    I've introduced the color picker into JMyron, I'm grabbing pixel values of the screen but the problem with it is that the mouse Events and the control events for controlP5 are conflicting. When I set the trackcolor to a color I click on, the RGB value is set. However, when I click on a controlP5 slider, the mouse event comes into play and the slider doesn't release.

    JMyron + controlP5 iteration #3

    Published by Michael Doyle under JMyron, Processing, controlP5

    I've added extra functionality to the controlP5 UI. An additional slider has been added for all color values, similar to iteration #1. However, the difference is that when the Black and White slider is moved, the other RGB sliders move to the exact the same location also, i.e., if I set the B&W slider to 100, the red, green and blue slider also match the value that I set it to (100). I can then change each RGB value from that and it will not affect the B&W slider. This allows me to find colors faster. Here's the code:

    Jmyron + controlP5 iteration #2

    Published by Michael Doyle under Audio, JMyron, Processing, controlP5

    From the old version, the problem that was happening was that there setting all RGB values to one slider value would only detect black to white colors. I changed so that now the RGB channels can now be all set individually. It works a lot better as can be seen from the screenshot. The bright blue areas with the green outline are the blogs, I've set it to detect the red boxes in this screenshot.

    Jmyron + controlP5 iteration #1

    Published by Michael Doyle under JMyron, Processing, controlP5

    I applied controlP5 to JMyron and the results are quite good. It's working in the same way as the previous example of manipulating audio with ess r2. What I have so far is that I'm setting the RGB channel to a specific value using controlP5. I'm also setting the sensitivity of the color value and the min pixel density with controlP5.
    I'm using an old example from the JMyron library which is finding the globEdgePoints and connecting them up. I have to change this to my averaging script.

    Here's the script:

    import JMyron.*;
import controlP5.*;
 
JMyron m;
ControlP5 controlP5;
 
int findcolor = 0;
int tracetolerance = 40;
int tracesize = 10;
 
void setup(){
  size(720,576);
  m = new JMyron();
  m.start(width,height);
  frameRate(30);
 
  println("Myron " + m.version());
  noFill();
 
  controlP5 = new ControlP5(this);
  controlP5.addSlider("findcolor",0,255,0,10,10,10,50).setId(1);
  controlP5.addSlider("sensitivity",0,255,40,10,140,10,50).setId(2);
  controlP5.addSlider("detect size",0,400,40,60,140,10,50).setId(3);
}
 
void draw(){
  m.maxDensity(tracesize);
  m.trackColor(findcolor,findcolor,findcolor,tracetolerance);
  float ir,ig,ib;
  m.update();//update the camera view
  int[] img = m.image(); //get the normal image of the camera
 
  //draw what the camera sees
  loadPixels();
  for(int i=0;i
