1. Consider a hypothetical Digital Image Processing (DIP) system of 8-bit images in which the images have an area/object of interest usually at higher intensity values (greater than or equal to 200) and a background consisting of lower intensity values (less than or equal to 99). The images also have unwanted elements appearing at intensity value between 100 to 200. Answer the following:

1. Specify an Intensity Transformation (IT) function to process the above images that will preserve the background, eliminate the unwanted elements and fix the intensity of the area of interest to 150. You can specify the IT either through equations or graphically. 6 marks
2. Apply the above IT in part i) to the following 8-bit image of size 3x3 pixels and find the output value: 4.5 marks

210	115	77
225	56	160
63	230	15

2. Apply the weighted average filter mask to the center pixel of the following 8-bit image of size 3x3 pixels and find the output value. For full marks you must show all steps of your work: 4.5 marks
