I tried this but my cam shows screen black with a red dot on top right corner.

please help.

thanking you in anticipation

Sorry for the late reply. I have not yet updated my sketches for the Processing 2.0 beta versions. However, if you download the source code there is a simple change that should do the trick: in the class `mycapture', in the method `get_image()', add as a first line:

1. cam.read();

Andreas

1.  public mycapture (PApplet pa, int w, int h) {
2.     _w=w;
3.     _h=h;
4.     cam=new Capture(pa,_w,_h);  
5.     cam.start();
6.   }

I am not very good at understanding Java errors myself, but this looks as if it cannot find OpenCV. Have you installed the OpenCV framework (which is independent from Processing)?

Andreas

Its working fine but after 5-8 minutes it getting hang and gives an error " outof memoryError: you may need to increase the memory in preferences ". 

While program running CPU usage is also very high

 Is there any solution to make it more perfect.

Thanking you in anticipation

Hi,

I do not experience the memory problems. Maybe you need to increase the available memory for Java: if you run it from Processing you can set a higher value in Preferences->Increase maximum available memory to

(I have set this to 1024MB). If you run it as an application you can change the memory allocation with

command line switches, see e.g.:

http://stackoverflow.com/questions/2294268/how-can-i-increase-the-jvm-memory

The CPU load is unfortunately very high. I have tweaked this to run OK on our machines but just about. There is not much you can do - but you can try to play with different framerates (fps=...) or try to use smaller images (w,h,w1,h1). But of course both will effect the quality of the result.

  Emask = loadImage("ripples.gif");

  create_blur(Emask);

  timer1=millis();

  timer2=millis();

how do i make Emask to detect class animation? like in this link  http://processing.org/learning/topics/animatedsprite.html

i want the Emask to get my animated image by refering to the class animation can u teach me? because i make animated gif image by photoshop, but it didnt work (animation wont play). help me please

I cannot teach you Processing, so I would recommend that you try to play with some easier examples first. 

But I can show you how to use an animated gif in my sketch. You need to download the library gifAnimation at  http://www.extrapixel.ch/processing/gifAnimation/

and then change the code as follows:

In the `you_are_einstein' tab at the top import the library as

1. import gifAnimation.*;

Then where the Emask image is declared add a Gif declaration:

In setup() you need to load and start your animated gif:

And finally in draw() you replace the image command for Emask with a new one for the gif so that it reads:

i have installed OpenCV1.0 using processing 1.5.1 on win7 32bit and AMD processor

but after a quick scan it does not look as if there is a clear solution. Checking that you have all the dll files of the right version might help.

Andreas

1.   //image(blurM[blur_idx], fx,fy,Iwidth, Iheight);
2.     image(myAnimation, fx, fy, Iwidth, Iheight);

Andreas

and then, make it to track the audience face instead of an image..
