After we get the residual block (`predicted partition - real partition`), we can **transform** it in a way that lets us know which **pixels we can discard** while keeping the **overall quality**. There are some transformations for this exact behavior.
Although there are [other transformations](https://en.wikipedia.org/wiki/List_of_Fourier-related_transforms#Discrete_transforms), we'll look more closely the discrete cosine transform (DCT). The [**DCT**](https://en.wikipedia.org/wiki/Discrete_cosine_transform) main features are:
Although there are [other transformations](https://en.wikipedia.org/wiki/List_of_Fourier-related_transforms#Discrete_transforms), we'll look more closely at the discrete cosine transform (DCT). The [**DCT**](https://en.wikipedia.org/wiki/Discrete_cosine_transform) main features are:
* **converts** blocks of **pixels** into same-sized blocks of **frequency coefficients**.
* **compacts** energy, making it easy to eliminate spatial redundancy.
