" exclude hole pixels from (Ru)c? An answer such as "the background is pixels of (Ru)c that are not hole pixels" is not acceptable. (Hint: Use tt connectivity) 2.20 Consider the image segment shown in the figure that follows. a. * As in Section 2.5 IU , let V={ 0,1} be the set of intensity define adjacency Compute the lengths of the shortest 4-, 8-, and between p and q in the following image. If a particular path does between these two points, explain why 3121(q)22021211(p)1012 b. Repeat (a) but using V={1,2}. 2.21 Consider two points p and q. a. * State the condition(s) under which the D4 distance between pa " exclude hole pixels from (Ru)c?
