Description

In this assignment, you are going to implement a discrete cosine transform described as follows. To facilitate your implementation, you need to use your assignment 1.

First, you need to read an argument (quality) from the command prompt, which will be used to create a quality matrix. Then, do the following steps.

1. Create an Init(quality) function to initialize a matrix T and a matrix Q where T is the cosine coefficient matrix and Q is the quality matrix. For detailed calculation, see Section 2.
2. Given a matrix M, compute its average and subtract its average from it
3. Perform matrix multiplication: D = T M T' where T' is the transpose of matrix T
4. Perform element-wise division: C = D / Q
5. PrintMatrix(C)
6. Perform element-wise multiplication: R = Q * C
7. Perform matrix multiplication: M2 = T' R T where T' is the transpose of matrix T
8. Add back the average to M2
9. PrintMatrix(M2)
