This first image is of a woman jogging on the beach. This image represents a high level system of perceived motion. The woman's form is recognized first as opposed to her jogging motion. Another motion is cue is that the woman is moving to the right of the image frame. The camera follows the woman's path as she jogs along the beach, this is due to relative movement. The camera anticipates her movement and allows enough room for her to catch up.
I'm guessing that the second image is a sports poster. This is an example of low level motion perception. This is due to the fact that the motion of the balls is seen first as opposed to the object itself. The motion of the balls are seen by the blurred trail that is left behind them. The athletes in the image are also blurred which implies movement. Further, the color of the balls differs from the luminance of background. This is due to the First-Order of perceived motion.
