In this problem you will work through a toy example of lossy compression of digital
images. Suppose you have a row of 8 grayscale pixels. Let
[100, 50, 200, 150, 175, 25, 40, 200]
represent the light intensities of each pixel in a sample image.
(a) What do the eight standard basis vectors represent in terms of this image? What
does a linear combination of these vectors represent? What do the coordinates
of a vector represent?
