Subtract an image from a video stream

[jknowles]

Hi

I was not having much luck looking online so was hoping someone had done this before.

We are doing some laser interferometry work and want to or able to subtract an image from a real time view from a camera. Has anyone done this before? It's maybe not an image problem but more hardware/interface related but was hoping to get some pointers. For info the camera is a Guppy and reads to a FireWire card

Thanks in advance

Hi Jonathan,

Depending on if there is hardware support for your camera (maybe just through the firewire interface?), you should be able to do this with a relatively simple BeanShell script using µManager (https://www.micro-manager.org/). They have their own mailing list that may be helpful if you are not familiar with it: https://www.micro-manager.org/wiki/Micro-Manager%20Community

HTH,

John
