5. Day 2: Pixel Face Take a picture of their own face Take a picture of their own face Upload Upload Magnify Magnify Count how many pixels wide and long in their face Count how many pixels wide and long in their face

6. Before and After Magnification

7. Two Phase Flow Give students pictures of two phase flow; each group gets a different picture Give students pictures of two phase flow; each group gets a different picture Use Transparency overlay of graph paper to represent pixels Use Transparency overlay of graph paper to represent pixels Mark gas as white and liquid as black Mark gas as white and liquid as black Students count and calculate fractions of liquid and gas and do a mass balance for the jet Students count and calculate fractions of liquid and gas and do a mass balance for the jet

17. Pre/Post Test When sampling an image spatially, the sampling rate might have units of ____________. When sampling an image spatially, the sampling rate might have units of ____________. pixels/cmAnswer pixels/cmAnswer pixels/sec pixels/sec cm/pixel cm/pixel pixels pixels

18. Spatial quantization refers to the process by which we assign Spatial quantization refers to the process by which we assign the number of pixels in an image. Answer the number of pixels in an image. Answer the frame rate of a movie. the frame rate of a movie. the shape of the pixels in an image. the shape of the pixels in an image. the numbers assigned to each pixel. the numbers assigned to each pixel.

19. A picture that has many small details would need to be sampled with A picture that has many small details would need to be sampled with a large pixel size. a large pixel size. a high spatial sampling rate. Answer a high spatial sampling rate. Answer a high bit quantization level. a high bit quantization level. a low bit quantization level. a low bit quantization level.
