Refer to Fig. 10.7 in answering the following questions.

FIGURE 10.7 (a) Image of a wire-bond template. (b) Result of processing with the +45° line detector mask in Fig. 10.6. (c) Zoomed view of the top left region of (b). (d) Zoomed view of the bottom right region of (b). (e) The image in (b) with all negative values set to zero. (f) All points (in white) whose values satisfied the condition g ≥ T, where g is the image in (e). (The points in (f) were enlarged to make them easier to see.)

(a) Some of the lines joining the pads and center element in Fig. 10.7(e) are single lines, while others are double lines. Explain why.
