A megapixel is a unit equal to one million pixels, used to measure the resolution of a digital image. For a given input image, you can find the pixel count by simply multiplying the number of horizontal pixels by the number of vertical pixels. Then to get the number of megapixels you divide by a megapixel (a million pixels).
"Master" is one operation, "encoder" is one operation, and "shifter" is one operation per step. However, the identity master have zero cost, as well as the trivial shifter (the one that doesn't touch the image).
