There are eight standard DCT variants, of which four are common. The most common variant of discrete cosine transform is the type-II DCT, which is often called simply the DCT. This was the original DCT as first proposed by Ahmed. Its inverse, the type-III DCT, is correspondingly often called simply the inverse DCT or the IDCT.
Finally, they propose modifications and show how the DCT method can be further strengthened. All in all, they conclude that the DCT is an adequate method to research Romance prosody (as well as the prosody of other languages) and that future research should continue to consider how to further refine and improve this data collection instrument ...
DCT can be a plausible theory to Christians because the traditional conception of God as the creator of the universe parallels the idea that he created moral truths. The theory is supported by the Christian view that God is all-powerful because this implies that God creates moral truths, rather than moral truths existing independently of him ...

The modified discrete cosine transform (MDCT) is a transform based on the type-IV discrete cosine transform (DCT-IV), with the additional property of being lapped: it is designed to be performed on consecutive blocks of a larger dataset, where subsequent blocks are overlapped so that the last half of one block coincides with the first half of the next block.

Trellis quantization is an algorithm that can improve data compression in DCT-based encoding methods. It is used to optimize residual DCT coefficients after motion estimation in lossy video compression encoders such as Xvid and x264. Trellis quantization reduces the size of some DCT coefficients while recovering others to take their place.
