Elya –

In v7.0, try aviread. This has straightforward syntax for reading a single frame – you could just embed in a for loop if that’s appropriate.

Readers with newer versions should check out mmreader – introduced on Windows in R2007b, Mac in R2008a.

Hi Szymon,

With the Image Acquisition Toolbox, you can acquire images or video into Simulink and/or MATLAB. For Simulink, you would use the “From Video Device” block. This supports USB web cameras, as well as a broad range of frame grabbers and scientific digital cameras. For more information on the supported hardware, look here: http://www.mathworks.com/products/imaq/supportedio.html
