Given list of quadrilaterals (from image processing), are there any properties/calculations that can filter out those that are not perspective projection of a target rectangle of **specific aspect ratio**?

For example, **a square** cannot be the image of **an A4 paper**. Can we generalize this concept to filter out more quadrilaterals?
