MCQs on Line Detection in Digital Image Processing

1.

For finding horizontal lines we use mask of values

[-1 -1 -1; 2 2 2; -1 -1 -1]
[2 -1 -1; -1 2 -1; -1 -1 2]
[-1 2 -1; -1 2 -1; -1 2 -1]
[-1 -1 2; -1 2 -1;2 -1 -1]

2.

For finding lines at angle 45 we use mask of values

[-1 -1 -1; 2 2 2; -1 -1 -1]
[2 -1 -1; -1 2 -1; -1 -1 2]
[-1 2 -1; -1 2 -1; -1 2 -1]
[-1 -1 2; -1 2 -1;2 -1 -1]

3.

If all lines in the direction of defined direction of mask are wished to be found then we use

thick edges
thin edges
thresholding
enhancement

4.

Masks for detection of specific lines are called

isolated
tuned
isomorphic
isotropic

5.

For finding vertical lines we use mask of values

[-1 -1 -1; 2 2 2; -1 -1 -1]
[2 -1 -1; -1 2 -1; -1 -1 2]
[-1 2 -1; -1 2 -1; -1 2 -1]
[-1 -1 2; -1 2 -1;2 -1 -1]
