Implementation of One-Dimensional Discrete Cosine Transform (DCT1) with Butterfly Algorithm

DCT1 computes one-dimensional discrete cosine transform using butterfly algorithm architecture, while DCT2 extends this approach to two-dimensional signal processing; both implementations optimize frequency domain conversion through efficient computational structures
