DCTorch: Discrete Cosine Transforms for PyTorch

DCTorch is a Python library providing fast discrete cosine transform (DCT) and inverse discrete cosine transform (IDCT) implementations optimized for PyTorch tensors. It enables efficient frequency domain analysis and manipulation within deep learning models, supporting 2D and 3D transforms. The current version is 0.1.2, and it appears to be actively maintained with recent commits.
