Algorithms for computing the Discrete Cosine Transform Type 4
Structs
DCT4Naive |
Naive O(n^2 ) DCT Type 4 implementation |
DCT4ViaDCT3 |
DCT Type 4 implementation that converts the problem into two DCT type 3 of half size. If the inner DCT3 is O(nlogn), then so is this. |
DCT4ViaFFTOdd |
DCT Type 4 implementation that converts the problem into an O(nlogn) FFT of the same size. |
Traits
DCT4 |
An umbrella trait for algorithms which compute the Discrete Cosine Transform Type 4 (DCT4) |
