1. Compulsory Question
a. Give a brief definition of each of the following terms.
i. image processing
ii. border ownership
b. The RGB channels for a 3-by-3 pixel colour image are shown below.
Convert this RGB image to a greyscale representation using an equal
weighting for each channel. Assume the greyscale image is represented
using 8 bits per pixel.
c. The array below shows the intensity values in a 3-by-3 pixel greyscale
Calculate the 2-by-2 pixel image that would result if Ic was convolved
with the 2-by-2 pixel mask, H:
d. Below is a 2-by-2 pixel greyscale image.
This image is to be up-sampled by a factor of 1.5, so as to become
a 3-by-3 pixel image. Calculate all the pixel values of the up-sampled
image using bilinear interpolation to fill-in missing values.
e. Below is a 3-by-3 pixel greyscale image.
Convert this image to binary format using a threshold of 100.
f. Below is a 3-by-3 pixel binary image.
Write down the new binary image that results from performing the
following morphological operations on If, assuming each pixel has 4
neighbours (horizontal and vertical).
