A digital image can be transformed into a set of coefficients using a reversible, linear transform, such as the discrete Fourier transform and the discrete cosine transform. The coefficients thus obtained can be quantized and coded for data compression. This is a lossy compression technique. It is called transform coding in the literature.
**Tasks** 1.
1. Write a computer program to implement the following transform coding schemes.
Casee1
Discrete Fourier Transform
8 x 8
8-largest coding
case 2
Discrete Cosine Transform
8 x 8
8-largest coding
You can use MATLAB or Visual C++ as the programming language.
