Detailed Description

Information about a block of wavelet coefficients.

In this context, a block refers to the detail coefficients of a particular wavelet decomposition level. For example, a 512x512 image is first decomposed into a 256x256 average (this is then again decomposed recursively) and 3 256x256 detail coefficients. These 3 256x256 detail coefficients make up a so-called block.
