live FFT

[Brian Pauw]

Dear all,

For a demonstration of diffraction/scattering, I would like to show a live FFT of the camera input on my mac. When I choose "FFT" in ImageJ, however, only the then current image is transformed. Is there a method or plugin to make this process continuous?

Yours sincerely,


Brian R. Pauw.

You could add an ImageListener to the ImagePlus of your live display
window, so that it runs an FFT of that Image and puts it into the
ImageProcessor of another image window. Can be done with a tiny
script.

Can someone describe briefly how to get "live" image processing
running through ImageJ on a Windows or Linux environment? I'm
comfortable working with stills but I am not sure where to start with
live video.

Thanks for any pointers.

Chuck
