"""H.264 8x8 Integer Inverse Transform for High Profile. The 8x8 IDCT is used for I_8x8 macroblocks in High profile. Uses 8-point butterfly operations with integer arithmetic. H.264 Spec Reference: ...

This code demonstrates a process of transforming audio signals into images using the Discrete Cosine Transform (DCT) and then reconstructing the audio signals from the images using the Inverse DCT ...

Abstract: This paper proposes an efficient one-dimensional (1-D) N-point discrete cosine and inverse discrete cosine transform (DCT/IDCT) architectures using sub-band decomposition algorithm. Based on ...
