Any suggestion will be appreciated. Thank you in advance, -Sokol Hello Steve,

It's something we're looking at. Walid—The Image Acquisition Toolbox does not support the GigE standard. It’s something we’re looking at.

I have a line scan camera with this standard of communication and I want to use Mathlab image processing toolbox to process images “on line” that were grabbed from the camera. Thank you for your answer. He Steve

The scene in which photos are taken from the mobile camera rotating 360 degrees around the bad man. Then its sent for processing in which the 3-d model is reconstructed and infact a hardware builds a real 3-d mask out of it. The hardware also paints the mask. This scene was so cool and it uses a very apt software-hardware integration of an image processing application. For me its Mission Impossible-3.

The person was just a small face in a large crowd of screaming hockey fans, and at one point one of the characters looking at the security footage demanded that the tech person zoom into the image further and clean it up, to which the tech person responded, "I could zoom in further, but all you would see is a blur: I only have two pixels for his nose." I cheered. Of course, there’s also the TV shows and movies that get it *right*, like Due South, where there was a potential criminal caught on videotape.

Last night I saw Transformers and an improbably attractive expert in signal analysis uttered the line "It's time to forget Fourier transfers and think quantum mechanics." Someone may like check the precise wording if they happen to see the movie but she definitely said "transfers." Needless to say, neither Fourier transfers nor quantum mechanics were relevant to the scene. In fact, they may have missed an ideal opportunity to embed a nerdy in-joke connecting transform theory with the title of the movie. Never mind.
