2D Discrete Cosine Transform (2D-DCT) is well know and wide used algorithm for imgage compression. All logic behind jpeg compression is based on DCT. We can also implement DCT on 3D matrix such as videos. In that project, we reimplemented some part of the paper which was on fast versions of 3D DCT and its inverse method named 3D IDCT .
