Question 3

+2 marksNumerical answer

Consider the grayscale image shown below:

[20302530404510403520152030255050403515301035252045]\begin{bmatrix} 20 & 30 & 25 & 30 & 40 \\ 45 & 10 & 40 & 35 & 20 \\ 15 & 20 & 30 & 25 & 50 \\ 50 & 40 & 35 & 15 & 30 \\ 10 & 35 & 25 & 20 & 45 \end{bmatrix}

If a median filter with a 3×33 \times 3 neighborhood is applied to this image with a stride of 1 and no padding, __________ will be the value at position (2,2)(2, 2) in the filtered image? (Assume that the top-left pixel coordinate of output image is addressed as (1,1)(1, 1))?
