Q $3($b$)$

$[6$ Marks$]$

Outline the operation of the $33$ Chamfer Algorithm based Distance Transform. Apply

this approach to the binary image segment illustrated in Figure Q$3\mathrm{.}3.$ Clearly show

how the Chamfer transform values are calculated. What are the limiting factors to this

approach? Outline the reasoning for the diagonal weighting in the $33$ masks used in

this technique.
