A distance function D between two pixels p and q is a valid
distance function iff D >0 when 
In general in digital image processing the smallest coordinate of a pixel start from (0,0) and thus pixel coordinates can have only non-negative values.
Hence, px, py, qx, and qy have non-negative values.
with equality held in each case for p = q = (0,0)
Therefore the given functions are valid distance functions.

Consider the following arguments. If an argument is valid, then present a proof sequence; otherwise, prove that the argument is invalid. You are forbidden to use truth tables to justify your answers (but, you may use them otherwise). ((p → r) ∨ (q → r)) → ((p ∨ q) → r) ((q → r) ∧ (p → (q ∨ r))) → (p → r) ((p → (q ∧ r)) ∧ (s → r) ∧ (s → t)) → (t →...
