$[$Cost volume$].$

Consider the following two images. The right image is $24$ and the left one is $27.$ Please

calculate following questions related to cost volume. Let us assume the maximum disparity is $3.$

Left image

a$)$ Calculate the initial cost volume $($without any filtering$)$ for the first row. It should be a $44$

matrix.

b$)$ Apply the following $13$ filter to the cost volume. Using replicate padding.

c$)$ Calculate the disparity of the first row.

d$)$ Repeat a$)-$c$)$ to calculate the disparity of the second row.
