Unscramble the Blue Letters

So how do we do all that? We basically analyze the changes in the light that are recorded at every pixel in the video over time, and then we crank up those changes. We make them bigger so that we can see them. The tricky part is that those signals, those changes that we're after, are extremely subtle, so we have to be very careful when you try to separate them from nsioe that always exists in videos. So we use some clever image processing tqecnhiues to get a very auacrcte mumneeersat of the color at each pixel in the video, and then the way the color changes over time, and then we amplify those changes. We make them bigger to caetre those types of enhanced videos, or mingaiefd videos, that actually show us those changes.

We make them bigger so that we can see them. The tricky part is that those signals, those changes that we're after, are extremely subtle, so we have to be very careful when you try to separate them from noise that always exists in videos. So we use some clever image processing techniques to get a very accurate measurement of the color at each pixel in the video, and then the way the color changes over time, and then we amplify those changes. We make them bigger to create those types of enhanced videos, or magnified videos, that actually show us those changes.
