Suppose we have two images at two different times: I(x,y,t) and I(x,y,t+1). How to estimate pixel motion from image l(x,y,t) to l(x,y,t+1)?
A. Put two images on top of each other and calculate the closest distance of I(x,y,t) and I(x,y,t+1)
B . Given a pixel in I(x,y,t), look for nearby pixels of the same color in I(x,y,t+1)
C. Use the interpolation method to estimate the next positions of I(x,y,t).
D. Based on the color of each pixel at the position I(x,y,t) relative to the overall image at time t+1
