For each of the following properties of edge detectors, indicate whether the Canny edge detector or

the Marr$-$Hildreth detector is better with respect to this property, and explain briefly why.

a$)$ Fewer number of parameters that must be set.

b$)$ Closed chains of edges detected.

c$)$ Computes the edge orientation.

d$)$ Better localization of the true edge position.

e$)$ Can be implemented more efficiently $($i$.$e$.,$ faster execution time$).$

f$)$ Requires non$-$maximum suppression to thin edges.

g$)$ Is an isotropic operator.

h$)$ Less likely to round corners where the boundary curvature is high.

i$)$ Less sensitive to noise.
