Identifying u and v

Given the following two images from subsequent frames, identify the image frame velocity vector (u,v) .

The origin is at the top left of the image. The x axis points right and the the y axis points down.

What is u for the above images?

SOLUTION: 1

What is v for the above images?

SOLUTION: -3

Now, consider the following two images of a long vertical line taken at subsequent frames.

What is u for the above images?

SOLUTION: 1

What is v for the above images?

SOLUTION: Impossible to determime
