== COSINE TRANSFORMATION(A Discrete Cosine Transform for Real Data) ==

A The Cosine_Transform is a simple C++ library which demonstrates properties of the Discrete cosine Transform for real data. The Discrete Cosine Transform for Real Data or DCT is used to create jpeg (compressed images). The formula used here is: C(u,v) = | (√1/n) , if u=0; 0≤v≤n-1 |(√2/n) * cos[((2*v+1)π*u)/2n], if 1≤u≤n-1; 0≤v≤n-1 Where, u is the row index, v is the column index and n is the total number of elements in a row/column in the matrix respectively. This [https://www.youtube.com/watch?v=tW3Hc0Wrgl0 Link] can be used for better understanding of the above formula.   Here is the [https://people.sc.fsu.edu/~jburkardt/cpp_src/cosine_transform/cosine_transform.html source code] used.
