identify components on a conveyor belt. The table below represents a

8*10 array of pixels and each cell gives the gray level value of the

corresponding pixel.

60 59 58 57 59 45 25 5

55 60 59 61 55 40 12 11

59 58 60 60 11 12 10 10

54 55 58 25 10 11 11 58

59 6 20 15 11 10 55 59

60 59 15 12 15 10 60 60

60 15 10 11 10 12 60 59

55 14 9 8 11 58 62 60

10 11 15 11 12 59 61 60

9 10 11 12 60 57 59 55

Construct an histogram for the array and select a threshold value for the image

represented above. Hence, convert the above gray level picture

representation into a binary image representation consisting of white image

on a black background.
