Distance between pixels is the distance between two pixels in an image which also exist in given set of values(V).

Types of Distances

City Block Distance(D₄): |xp -xq| + |yp -yq|
Chess Board Distance(D₈): max(|xp -xq|,|yp -yq|)
Mixed Distance(D_m) Use the values in the V to trace the path. Here the D₄ and D₈ doesn’t depend on gray level or value in V.
