Unscramble the Blue Letters

So how do we do all that? We bacslaliy 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 noise that always estixs in veoids. So we use some clever imgae processing techniques to get a very accurate measurement of the cloor at each pixel in the video, and then the way the color changes over time, and then we apmfily those changes. We make them bigger to create those types of enhanced videos, or magnified videos, that actually show us those changes.

So how do we do all that? We _________ 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 noise that always ______ in ______. So we use some clever _____ processing techniques to get a very accurate measurement of the _____ at each pixel in the video, and then the way the color changes over time, and then we _______ those changes. We make them bigger to create those types of enhanced videos, or magnified videos, that actually show us those changes.

Original Text

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 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.
